About Maternally Inherited Leigh Syndrome and NARP Syndrome

What is Maternally Inherited Leigh Syndrome and NARP Syndrome?

Maternally Inherited Leigh Syndrome (MILS) is a rare, inherited mitochondrial disorder that affects the central nervous system. It is caused by a mutation in the mitochondrial DNA, which is passed down from the mother to her children. Symptoms of MILS include developmental delay, seizures, vision and hearing loss, and muscle weakness.

NARP Syndrome (Neuropathy, Ataxia, and Retinitis Pigmentosa) is a rare, inherited mitochondrial disorder that affects the central nervous system. It is caused by a mutation in the mitochondrial DNA, which is passed down from the mother to her children. Symptoms of NARP Syndrome include progressive muscle weakness, ataxia, vision loss, hearing loss, and seizures.

• Abnormalities in

What are the causes of Maternally Inherited Leigh Syndrome and NARP Syndrome?

Maternally Inherited Leigh Syndrome (MILS) is caused by mutations in the mitochondrial DNA. NARP Syndrome (Neuropathy, Ataxia, and Retinitis Pigmentosa) is caused by mutations in the mitochondrial ATPase 6 gene.

What are the treatments for Maternally Inherited Leigh Syndrome and NARP Syndrome?

Maternally Inherited Leigh Syndrome:

1. Dietary modifications: A low-protein diet may be recommended to reduce the amount of toxic metabolites in the body.

2. Vitamin supplementation: Vitamin B12, thiamine, and coenzyme Q10 may be recommended to help reduce symptoms.

3. Antioxidants: Antioxidants such as vitamin E, selenium, and coenzyme Q10 may be recommended to help reduce oxidative stress.

4. Medications: Medications such as acetazolamide, topiramate, and zonisamide may be recommended to help reduce symptoms.

5. Surgery: Surgery may be recommended to help reduce symptoms.

NARP Syndrome:

1. Dietary modifications: A low-protein diet may be recommended to reduce the amount of toxic metabolites in

What are the risk factors for Maternally Inherited Leigh Syndrome and NARP Syndrome?

Maternally Inherited Leigh Syndrome:

1. Mutation in the mitochondrial DNA
2. Inheritance from a mother with a mitochondrial DNA mutation
3. Family history of Leigh Syndrome

NARP Syndrome:

1. Mutation in the mitochondrial DNA
2. Inheritance from a mother with a mitochondrial DNA mutation
3. Family history of NARP Syndrome
4. Exposure to certain environmental toxins or drugs

Is there a cure/medications for Maternally Inherited Leigh Syndrome and NARP Syndrome?

Maternally Inherited Leigh Syndrome (MILS) is a rare mitochondrial disorder that is caused by a mutation in the mitochondrial DNA. There is currently no cure for MILS, but medications can be used to help manage the symptoms. These medications include anticonvulsants, muscle relaxants, and medications to help with breathing.

NARP Syndrome (Neuropathy, Ataxia, and Retinitis Pigmentosa) is a rare genetic disorder that is caused by a mutation in the mitochondrial DNA. There is currently no cure for NARP Syndrome, but medications can be used to help manage the symptoms. These medications include anticonvulsants, muscle relaxants, and medications to help with vision and breathing.
