Canine neuronal ceroid lipofuscinosis (NCL) is a rare but serious neurodegenerative disease in dogs characterized by the accumulation of ceroid lipofuscin in nerve cells. These deposits lead to progressive neurological impairments and ultimately to the death of the affected animals.

Causes and Pathogenesis of Canine Neuronal Ceroid Lipofuscinosis (NCL)

Canine neuronal ceroid lipofuscinosis (NCL) is one of a group of lysosomal storage diseases caused by genetic defects. These defects lead to a disturbed function of the lysosomes, the “recycling centers” of the cell, which means that waste products can no longer be broken down properly. Below we will go into detail about the causes and the disease process.

Genetic mutations as the main cause

The basis of ceroid lipofuscinosis in dogs NCL are mutations in genes that encode lysosomal enzymes or transport proteins. These proteins play an essential role in the breakdown of metabolic products within the lysosomes. A mutation in these genes can result in a dysfunction that causes the accumulation of undigested or partially degraded substances such as ceroid lipofuscin .

Frequently affected genes are:

  • CLN1 (PPT1) : Encodes an enzyme that removes palmitoyl residues from proteins.
  • CLN2 (TPP1) : Encodes a tripeptidyl peptidase enzyme that breaks down proteins into smaller peptides.
  • CLN6 : Responsible for the transport of certain molecules within the cell.
  • CLN8 : Involvement in lipid processing and transport.

The specific mutation and affected gene may vary depending on the dog breed.

Pathogenesis: How the disease occurs

The pathogenesis of ceroid lipofuscinosis in dogs NCL is a complex process that gradually leads to the loss of neuronal functions:

  1. Malfunction of the lysosomes : The genetic mutation impairs the activity of one or more lysosomal enzymes. The result is an accumulation of ceroid lipofuscin, a pigmented waste product that cannot be further broken down in the cells.
  2. Accumulation of ceroid lipofuscin : This substance accumulates primarily in nerve cells, but also in other cell types such as glial cells. It is neurotoxic and leads to dysfunction and death of the affected cells.
  3. Neuronal cell loss : The progressive accumulation of the material causes inflammatory reactions and oxidative stress. This leads to degeneration and loss of nerve cells, particularly in the brain and retina.
  4. Neurological symptoms : With the loss of nerve cells, symptoms such as movement disorders, vision loss and cognitive deficits manifest themselves. These symptoms progressively worsen as more and more nerve cells are damaged.

Influence of external factors

Although the genetic mutation is the main trigger, environmental factors such as oxidative stress, diet or secondary metabolic disorders could influence the course of the disease. These factors are currently being investigated in research to develop a better understanding of disease progression.

Molecular mechanisms

A central component of the pathogenesis is the role of mitochondrial dysfunction. The accumulation of waste materials impairs the cell's energy production, further promoting cell death. In addition, there is an overactivation of inflammatory processes, which further increases the damage to the nerve cells.

Causes at a glance

Genetic factors

Genetic mutations play a central role. Defective genes can significantly affect the normal function of cells.

Environmental influences

Certain environmental factors such as pollutants or poor nutrition can negatively influence the course of the disease.

Metabolic disorders

Malfunctions in metabolism can lead to an accumulation of harmful substances in cells.

Hereditary predisposition

In many cases the disease is hereditary and is passed on through carriers within the population.

Affected dog breeds and their genetic predisposition

Neuronal ceroid lipofuscinosis (NCL) occurs in various dog breeds and is often linked to certain genetic mutations in a breed-specific manner. These mutations affect the functioning of lysosomal enzymes or transport proteins, which ultimately leads to the development of the disease. Below we provide a detailed overview of the dog breeds affected, their genetic characteristics and the course of the disease.

Overview of commonly affected breeds

1. English setter

  • Genetic mutation : CLN8
  • Inheritance mode : Autosomal recessive
  • Age of onset : Typically between 2 and 7 years

Importance of genetic testing for breeding

The affected dog breeds show that genetic predisposition plays a central role. Through targeted genetic testing, carrier animals can be identified and excluded from breeding. This is particularly important for breeds with a high hereditary risk in order to reduce disease incidence in the long term.

Cross-racial observations

Even if certain breeds are particularly frequently affected, mutations in similar genes can also occur in mixed breeds. Therefore, if ceroid lipofuscinosis in dogs NCL is suspected, it makes sense to also carry out genetic tests in mixed-breed dogs. In addition, some lines within the same breed have a higher prevalence, indicating a close relationship within the breeding base.

Clinical symptoms of canine neuronal ceroid lipofuscinosis (NCL)

The clinical symptoms of canine neuronal ceroid lipofuscinosis (NCL) are varied and depend largely on the affected dog breed, the specific genetic mutation, and the stage of the disease. Since it is a progressive neurodegenerative disease, the symptoms worsen over time and increasingly affect the quality of life of the affected animals. Recognizing the signs early can help make a diagnosis more quickly and improve management.

Early stage: First subtle changes

The initial symptoms of canine ceroid lipofuscinosis NCL are often difficult to recognize because they can be nonspecific and subtle. Typical early signs include:

  • Behavioral changes:
    • Restlessness, anxiety or mild irritability.
    • Withdrawal or decreased interest in social interactions and games.
  • Vision problems:
    • Difficulty seeing obstacles, especially in low light conditions.
    • Decreased responsiveness to visual stimuli, which may indicate the onset of retinal degeneration.
  • Cognitive impairments:
    • Confusion or difficulty following familiar commands.
    • Repeated disorientation, even in familiar surroundings.

Progressive symptoms: Significant neurological deficits

As the disease progresses, symptoms become more obvious and severe. Common clinical signs include:

  • Ataxia (coordination disorders):
    • Unsteady gait, frequent stumbling or swaying sideways.
    • Difficulty jumping or climbing stairs.
  • Muscle tremors and cramps:
    • Uncontrolled twitching or muscle tremors, especially in the limbs.
    • Seizures, which may increase in frequency and intensity.
  • Progressive vision loss:
    • Total blindness caused by degeneration of the retina (retinal degeneration).
    • Dogs often bump into furniture or walls and show signs of uncertainty in unfamiliar terrain.
  • Loss of the ability to learn and remember:
    • Dogs can forget previously learned commands or behaviors.
    • Confusion and disorientation, even when near familiar people or in familiar surroundings.

Late stage: Severe impairments

In the advanced stages of ceroid lipofuscinosis in dogs NCL, dogs are often severely impaired and require intensive care. Symptoms include:

  • Severe movement disorders:
    • Complete inability to coordinate or move.
    • Paralysis in the hind or front legs.
  • Increased behavioral problems:
    • Aggressive behavior or severe fears.
    • Increased barking, whining, or other signs of discomfort.
  • Cognitive degeneration:
    • Complete loss of orientation and awareness of the surroundings.
    • Dogs no longer respond to familiar stimuli such as their owners or familiar sounds.
  • Incontinence:
    • Loss of bladder and bowel control due to neurological deficits.

Symptom progression by race

The course of symptoms can vary depending on the dog breed. While some breeds experience loss of vision, movement disorders and seizures may predominate in others. The symptoms often occur within an age window that is typical for the breed, which can be helpful in making a diagnosis.

Different expression among individuals

Although the above symptoms are typical, they can vary in severity and order. Some dogs show early vision loss, while for others, movement problems are the first signs. The individual variation underlines the importance of a thorough clinical examination and, if necessary, genetic diagnosis.

Diagnosis of Canine Neuronal Ceroid Lipofuscinosis (NCL)

Diagnosis of canine neuronal ceroid lipofuscinosis (NCL) is challenging because early-stage symptoms are nonspecific and may also indicate other neurological diseases. However, a precise and early diagnosis is crucial to confirm the disease and to better assess the course of the disease. Below we review the key steps and methods used in diagnosing canine ceroid lipofuscinosis NCL.


1. Clinical examination

Diagnosis begins with a thorough clinical examination by the veterinarian , which takes into account the following aspects:

  • anamnese:
    • Onset and progression of symptoms.
    • Information on previous genetic diseases in the breeding line.
    • Abnormalities in behavior, ability to move or sensory perceptions.
  • Observation of symptoms:
    • Check for neurological deficits such as ataxia, muscle tremors, or vision loss.
    • Behavioral tests to detect cognitive impairments.

2. Imaging procedures

Imaging procedures are an important part of the diagnosis as they can reveal structural changes in the brain and other affected organs:

  • Magnetic resonance imaging (MRI):
    • Depiction of changes in brain regions such as the cerebellum and cerebral cortex.
    • Detection of atrophies (tissue loss) or deposits in specific brain regions.
  • Computed tomography (CT):
    • Less specific than MRI but helpful in detecting major structural abnormalities.

3. Eye exam

Examination of the retina can provide valuable information about the disease, as NCL is often associated with retinal degeneration:

  • Funduscopy:
    • Examination of the back of the eye for signs of pigment loss or retinal degeneration.
  • Electroretinography (ERG):
    • Measurement of the electrical activity of the retina in order to detect functional disorders at an early stage.

4. Genetic testing

Genetic testing is the most precise means of diagnosing NCL because it can identify specific mutations in the affected genes:

  • DNA analysis:
    • examined for breed-specific mutations in genes such as CLN1 , CLN5 , CLN6 , or CLN8
    • Identification of carrier animals (heterozygous) or affected animals (homozygous).
  • Advantages of genetic testing:
    • Early diagnosis, even before clinical symptoms appear.
    • Helpful for breeders to exclude carriers from breeding.

5. Biopsy and histological analysis

In certain cases, a biopsy may be performed to support the diagnosis:

  • Tissue samples:
    • Muscle or skin biopsies can be examined under a microscope to detect accumulation of ceroid lipofuscin.
  • Histopathology:
    • The samples show characteristic deposits that fluoresce in the affected cells when treated with certain dyes.

6. Laboratory tests

In addition to the diagnosis, laboratory tests can be carried out to rule out other causes:

  • Lysosomal enzyme activity:
    • Measuring the activity of specific lysosomal enzymes to identify defects.
  • CSF examination (spinal fluid):
    • Analysis for inflammatory or degenerative changes that may indicate NCL.

7. Diagnosis of exclusion

Because the symptoms of ceroid lipofuscinosis in dogs NCL can also occur in other neurological diseases, it is important to rule out alternative causes, such as: E.g.:

  • epilepsy
  • Degenerative myelopathies
  • Metabolic disorders

Importance of early diagnosis

Early diagnosis is essential to document the progression of the disease and to provide the animal and the owner with the best possible support. Although ceroid lipofuscinosis in dogs NCL is currently not curable, the diagnosis allows:

  • Targeted symptomatic treatment : Improving quality of life through appropriate therapeutic approaches.
  • Breeding decisions : Reducing the spread of NCL through genetic screening.
  • Research and Studies : Participate in clinical trials that explore new therapies and treatment options.

    • Using stem cells to regenerate damaged nerve tissue.

Prevention of Canine Neuronal Ceroid Lipofuscinosis (NCL)

Canine neuronal ceroid lipofuscinosis (NCL) is a genetic disease that can be greatly reduced through targeted preventive measures in dog breeding. Because the disease is inherited, the focus is on genetic testing, responsible breeding practices and educating breeders and dog owners. Good prevention is the key to sustainably reducing the spread of canine ceroid lipofuscinosis NCL in affected dog breeds.


1. Genetic testing as a basis for prevention

The main approach to preventing canine ceroid lipofuscinosis NCL is the use of genetic tests that allow accurate identification of carrier animals:

  • How the tests work:
    • DNA analysis can be used to detect mutations in specific genes such as CLN1, CLN5, CLN6 or CLN8.
    • Blood or saliva samples are sufficient to determine a dog's genetic predisposition.
  • Categorization of test results:
    • Free (homozygous healthy) : No mutation; the dog cannot pass on the disease.
    • Carrier (heterozygous) : The dog shows no symptoms but can inherit the mutation.
    • Affected (homozygous affected) : The dog has two mutated genes and develops the disease.
  • Advantages of genetic testing:
    • Early identification of affected or potential carriers.
    • Basis for targeted breeding decisions to prevent the disease from being passed on.

2. Responsible breeding practices

Breeders play a critical role in preventing NCL. With careful breeding management, the spread of the disease in the population can be minimized:

  • Exclusion of carrier animals from breeding:
    • Carriers should only be bred with genetically free dogs to eliminate the risk of affected offspring.
    • The exclusion of both carrier animals from breeding is recommended in order to remove the mutation from the breed in the long term.
  • Breeding programs with screening:
    • Reputable breeding clubs should make genetic testing mandatory for all breeding dogs.
    • Transparent communication of test results within the breeding community is essential.
  • Avoiding close inbreeding:
    • Because inbreeding increases the likelihood that carrier animals will meet, broad genetic diversity should be encouraged.

3. Education and awareness raising

Comprehensive education is critical to inform owners, breeders and veterinarians about the risks and prevention options of NCL:

  • Information for breeders:
    • Breeders should be informed about the importance of genetic testing, the inheritance of NCL and the consequences for offspring.
  • Advice for puppy buyers:
    • Buyers should specifically ask for genetic test results from the parents.
    • Transparency on the part of breeders strengthens trust and prevents the mutation from being passed on unconsciously.
  • Veterinary training courses:
    • Veterinarians should be able to advise on genetic testing and prevention measures.
    • Support with diagnostics and genetic counseling can help contain the disease in the long term.

4. Breed-specific prevention programs

Because certain breeds are more commonly affected, prevention programs tailored specifically to these breeds should be developed:

  • Breed clubs and associations:
    • Breed-specific clubs can set standards and guidelines for genetic testing.
    • Joint initiatives, such as databases of test results, promote transparency.
  • International cooperation:
    • Exchange genetic information between countries and breeding associations to expand the breeding base and minimize mutation worldwide.

5. Future prospects: advances in research

Science is continually working on new approaches to make genetic prevention even more effective:

  • CRISPR/Cas technology:
    • Research into correcting genetic defects in early stages of development could offer new opportunities in the future.
  • Further development of genetic testing:
    • More accurate and cost-effective tests that can be more easily used in breeding programs.
  • Long-term eradication of the mutation:
    • Through consistent prevention work, the mutation can be eliminated over generations.

Common Questions About Ceroid Lipofuscinosis in Dogs

What is neuronal ceroid lipofuscinosis (NCL) and how does it occur?

Neuronal ceroid lipofuscinosis (NCL) is a genetic neurodegenerative disease that occurs in both humans and dogs. It belongs to the group of lysosomal storage diseases in which breakdown products of cell metabolism cannot be broken down properly due to genetic defects. This disease leads to the accumulation of so-called ceroid lipofuscin deposits in the nerve cells. These substances consist of lipids and proteins that are normally broken down by lysosomal enzymes.
Through mutations in specific genes, such as B. CLN1, CLN2, CLN5 or CLN8, the function of the lysosomal enzymes is impaired. This disrupts the natural breakdown process and the substances that are not broken down accumulate in the cells. Nerve cells in the brain and retina of the eyes are particularly affected, leading to serious symptoms such as vision loss, movement disorders, cognitive decline and ultimately death. The disease is inherited in an autosomal recessive manner, which means that both parents must be carriers of the mutation for offspring to be affected.

What symptoms occur in dogs with NCL and how do they develop over the course of the disease?

The symptoms of NCL are varied and depend on the dog breed, genetic mutation and age of onset. The disease is progressive, meaning symptoms worsen over time. In the early stages, signs are often subtle and nonspecific, making diagnosis difficult.
Early stage :
Mild behavioral changes such as restlessness, fear or aggressiveness.
Subtle vision loss, initially manifested by difficulty in orientation, especially in poor lighting conditions.
First motor abnormalities such as unsteady gait or stumbling.
Progressive symptoms :
Significant movement disorders such as ataxia (loss of coordination) or muscle tremors.
Increased vision loss up to complete blindness due to retinal degeneration.
Cognitive impairments, e.g. B. Disorientation and forgetting learned commands.
Late stage :
Complete loss of ability to move due to severe ataxia or paralysis.
Incontinence and inability to perform basic tasks such as eating independently.
Severe behavior problems such as persistent whining or aggressiveness towards caregivers.
Life expectancy varies greatly and depends on the breed of dog and when the first symptoms appear.

How is NCL diagnosed and what role does genetic testing play?

Diagnosis of neuronal ceroid lipofuscinosis is a multistep process that includes clinical examinations, imaging tests, and genetic testing.
Clinical examination :
The veterinarian checks the dog's symptoms, such as: B. Ataxia, vision loss or behavioral changes.
Potential genetic disorders are considered based on the owner's medical history and description.
Imaging techniques :
Magnetic resonance imaging (MRI) can reveal changes in the brain, such as: B. Atrophies in certain regions.
Eye diagnostics by funduscopy or electroretinography (ERG) show retinal degeneration.
Genetic testing :
Genetic testing is the most precise method to detect NCL. They can be done through a simple blood or saliva sample.
These tests identify specific mutations associated with the disease and can clearly identify carriers and affected animals.
Genetic tests are important not only for diagnosis, but also for prevention in breeding. They help breeders identify carrier animals and prevent the mutation from spreading through targeted breeding decisions.

What treatment options are there for NCL and how can the lives of affected dogs be improved?

Although there is no cure for NCL, several measures can be taken to relieve symptoms and improve the quality of life of affected dogs:
Drug treatment :
Anticonvulsants such as phenobarbital help control epileptic seizures.
Antioxidants such as vitamin E or coenzyme Q10 can reduce oxidative stress in nerve cells.
Anti-inflammatory drugs or neuroprotective agents could slow the progression of the disease.
Nutrition :
Special diets containing omega-3 fatty acids and easily digestible proteins can support overall well-being.
Supplements like L-carnitine promote energy supply to cells.
Supportive care :
Physical therapy can help maintain mobility and prevent muscle loss.
Environmental adjustments such as removing obstacles and using assistive devices make everyday life easier.
Emotional support :
Loving care and a structured daily routine offer the dog security and reduce stress.
The owner should pay attention to signs of discomfort and accompany the animal during difficult periods.
Treatment aims to provide the dog with as comfortable a life as possible, even as the disease progresses.

How can genetic testing and responsible breeding effectively prevent NCL?

Prevention of NCL is the responsibility of breeders and owners. Genetic testing is the key tool to prevent the spread of the disease:
Importance of genetic testing :
Genetic testing identifies carrier animals and affected dogs. Breeders can specifically decide which dogs are bred with each other.
By excluding carrier animals from breeding, affected offspring can be avoided.
Responsible breeding practices :
Breeders should only use animals that are genetically free of the mutation. Carriers can only be mated if the partner can be proven to be free.
A broad genetic base in breeding prevents inbreeding and reduces the risk of passing on defective genes.
Education and collaboration :
Breeders, veterinarians and clubs should work closely together to control the spread of NCL.
Buyers of puppies should be informed of the genetic test results of the parents.
Through consistent prevention and responsible breeding, the mutation can be eliminated from affected breeds in the long term.

Summary: Ceroid lipofuscinosis in dogs

Ceroid lipofuscinosis in dogs is a serious, genetic neurodegenerative disease characterized by the accumulation of ceroid lipofuscin in nerve cells. This rare disease belongs to the group of lysosomal storage diseases and affects numerous dog breeds. Affected dogs exhibit a variety of symptoms, including behavioral changes, movement problems, vision loss and cognitive deficits. Ceroid lipofuscinosis in dogs leads to a progressive deterioration in quality of life and ultimately death of the animal.

The cause of ceroid lipofuscinosis in dogs is genetic mutations that affect lysosomal enzymes or transport proteins. This means that waste products in the cells cannot be broken down properly, leading to the accumulation of ceroid lipofuscin. Nerve cells in the brain and retina are particularly often affected, causing the characteristic neurological symptoms. Inheritance is autosomal recessive, so both parents must be carriers of the mutated gene for offspring to develop the disease.

Dog breeds particularly susceptible to canine ceroid lipofuscinosis include English setters, border collies, dachshunds, Tibetan terriers and Australian shepherds. Each breed is associated with specific genetic mutations and a typical age window of disease onset. A breed-typical course of ceroid lipofuscinosis in dogs often enables an early suspected diagnosis, which can be confirmed by genetic tests.

Diagnosis of ceroid lipofuscinosis in dogs is made through a combination of clinical examination, imaging tests such as MRI, eye exams, and genetic testing. Genetic tests are particularly important because they can precisely detect the mutation in the affected genes. They not only help with diagnosis, but are also essential for preventive measures in dog breeding.

Although there is currently no cure for ceroid lipofuscinosis in dogs , the quality of life of affected animals can be improved through symptomatic therapies. These include the use of anticonvulsants to control seizures, antioxidants to reduce oxidative stress, and supportive measures such as physical therapy or modified diets. Loving care and a structured daily routine are also important parts of the management of ceroid lipofuscinosis in dogs .

Prevention of ceroid lipofuscinosis in dogs is a critical approach to minimizing the spread of the disease. Genetic tests are the most effective tool for identifying carrier animals and specifically excluding them from breeding. Responsible breeding practices that only use genetically free animals can eliminate the mutation in affected breeds in the long term.

Until then, prevention remains the most effective way to reduce ceroid lipofuscinosis in dogs

ceroid lipofuscinosis in dogs is a complex but preventable disease that can be effectively controlled through genetic testing and responsible breeding decisions. Through targeted measures, we can work together to protect the quality of life of our four-legged friends and enable ceroid lipofuscinosis in dogs

Combating ceroid lipofuscinosis in dogs requires a holistic approach that includes prevention as well as research, education and practical support.

A key step is the greater integration of genetic testing into breeding programs. Here, breeding clubs should not only set clear standards, but also introduce mandatory screening procedures for breeding animals. This makes it possible to ensure that carrier animals can be consistently identified and accordingly excluded or specifically mated in order to prevent ceroid lipofuscinosis in dogs Transparent documentation and international cooperation between breeding associations could additionally support this process.

In addition, education plays a key role. be better informed about the risks and genetic background of ceroid lipofuscinosis in dogs This could be achieved through training, specialist articles and awareness campaigns. The more knowledge available, the more likely pet owners can make informed decisions, such as when purchasing a puppy or dealing with a sick animal.

Research and development is also essential to minimize ceroid lipofuscinosis in dogs Advances in gene therapy could, for example, make it possible to directly correct defective genes or replace missing lysosomal enzymes. Studies on neuroprotective substances and innovative treatment approaches offer further hope. Close collaboration between scientists, veterinarians and breeders will be crucial to effectively implement these potential therapies.

It is important for affected dogs that their quality of life is maintained as much as possible. Owners should develop a plan early on to address the animal's needs. This includes adapting the environment to ensure safety, using supportive devices, and regular veterinary consultations. With loving care and well-thought-out management, dogs with ceroid lipofuscinosis live dignified lives, even as the disease progresses.

Ceroid lipofuscinosis in dogs is a serious but not insurmountable challenge. By acting responsibly and continually supporting research, we can reduce the impact of this condition and create a future where genetic diseases like canine ceroid lipofuscinosis no longer pose a threat to our four-legged friends. It is a collaborative effort between breeders, scientists, veterinarians and dog owners that makes the difference.

In order to ceroid lipofuscinosis in dogs , technical advances in diagnostics should also be used. Modern genetic testing techniques that are becoming faster, more accurate and more cost-effective could help screening programs be implemented more broadly. This would be beneficial not only to professional breeders, but also to pet owners who want to ensure that their dogs are not carriers of the affected gene. Access to such tests could be made easier through government or breeding funding programs.

Another crucial aspect is the emotional and psychological support of the owners of dogs with ceroid lipofuscinosis . The diagnosis of an incurable disease is stressful for many pet owners. Counseling services that, in addition to medical aspects, also deal with dealing with emotional stress can be an important source of support here. Exchanging ideas with other affected owners, for example in self-help groups or online forums, can help you better cope with everyday life with a sick animal.

The role of veterinarians is also crucial. They should receive regular training in order to recognize ceroid lipofuscinosis in dogs Veterinarians are often the first port of call when a dog shows symptoms, and their knowledge can help make the diagnosis more quickly and optimize the animal's quality of life.

Veterinary clinics could also develop specialized programs to care for dogs with ceroid lipofuscinosis . Such programs could include regular monitoring of the progression of the disease, adjustment of therapy plans, and monitoring of the animal through the various stages of the disease. In addition, veterinary research institutions could carry out studies with affected animals in order to gain new insights into the course of the disease and potential treatment approaches.

The long-term goal should be ceroid lipofuscinosis in dogs through genetic prevention measures. With consistent implementation of breeding programs based on genetic testing, future generations of dogs could be spared from this serious disease. It is important to maintain genetic diversity within the breeds in order to prevent other health problems.

Ceroid lipofuscinosis in dogs shows the importance of a holistic approach to animal health. Research, prevention, education and loving care of the affected animals form the basis for dealing with this disease. With a shared commitment from everyone involved, we can ensure that dogs who bring us so much joy and companionship receive the best possible support - and that future generations can grow up free from the threat of canine ceroid lipofuscinosis .
