Thiemann disease, familial form is a rare genetic disorder characterized by progressive muscle weakness, intellectual disability, and seizures. It is caused by mutations in the SLC25A12 gene, which is responsible for the production of a protein involved in the transport of mitochondrial metabolites. Symptoms typically begin in infancy or early childhood and can include hypotonia, delayed motor development, intellectual disability, seizures, and vision and hearing problems. Treatment is supportive and may include physical and occupational therapy, speech therapy, and anticonvulsant medications.

The symptoms of Thiemann disease, familial form, can vary from person to person, but typically include:

-Developmental delay
-Intellectual disability
-Seizures
-Movement disorders
-Feeding difficulties
-Growth retardation
-Hearing loss
-Vision problems
-Behavioral problems
-Speech and language delays
-Abnormalities of the head and face
-Abnormalities of the hands and feet
-Abnormalities of the heart, lungs, and other organs

The exact cause of Thiemann disease, familial form, is unknown. However, it is believed to be caused by a genetic mutation in the SLC25A13 gene, which is responsible for the production of a protein called citrin. This protein is involved in the transport of certain molecules within the mitochondria, the energy-producing organelles in cells. Mutations in this gene can lead to a buildup of these molecules, which can cause the symptoms of Thiemann disease.

The treatments for Thiemann disease, familial form, are largely supportive and symptomatic. Treatment may include physical therapy, occupational therapy, speech therapy, and nutritional support. Medications may be prescribed to help manage seizures, muscle spasms, and other symptoms. Surgery may be recommended to correct any structural abnormalities in the brain or spinal cord. In some cases, gene therapy may be an option.

1. Family history: Individuals with a family history of Thiemann disease, familial form, are at an increased risk of developing the condition.

2. Age: Thiemann disease, familial form, is more common in individuals over the age of 40.

3. Gender: Thiemann disease, familial form, is more common in males than females.

4. Ethnicity: Thiemann disease, familial form, is more common in individuals of European descent.

5. Genetic mutation: Individuals with a mutation in the GBA gene are at an increased risk of developing Thiemann disease, familial form.

Unfortunately, there is no cure for Thiemann disease, familial form. However, there are medications that can help manage the symptoms. These include anticonvulsants, muscle relaxants, and medications to help with sleep. Additionally, physical and occupational therapy can help improve mobility and quality of life.
