ICD-10: G11

Hereditary ataxia, classified under ICD-10 code G11, encompasses a group of genetic disorders characterized by progressive loss of coordination and balance due to dysfunction in the cerebellum and its connections. This condition can manifest in various forms, with Friedreich's ataxia being one of the most common types.

Clinical Description of Hereditary Ataxia

Definition and Symptoms

Hereditary ataxia refers to a range of disorders that are inherited and lead to ataxia, which is the lack of voluntary coordination of muscle movements. Patients typically present with symptoms such as:

• Gait Disturbances: Difficulty walking, often described as a staggering or unsteady gait.
• Coordination Issues: Problems with fine motor skills, affecting tasks like writing or buttoning clothing.
• Speech Difficulties: Slurred speech (dysarthria) may occur as the condition progresses.
• Vision Problems: Some patients may experience visual disturbances due to eye muscle weakness.
• Muscle Weakness: Progressive muscle weakness can develop, impacting daily activities.

Types of Hereditary Ataxia

Hereditary ataxias can be classified into several types based on genetic causes:

1. Friedreich's Ataxia: The most prevalent form, caused by mutations in the FXN gene, leading to degeneration of spinal cord and peripheral nerves.
2. Spinocerebellar Ataxias (SCAs): A group of disorders with various genetic mutations, each leading to different clinical features and progression rates.
3. Ataxia-telangiectasia: A rare disorder characterized by ataxia, immune deficiencies, and an increased risk of cancer, caused by mutations in the ATM gene.

Genetic Basis

Hereditary ataxias are primarily caused by genetic mutations that affect the function of neurons in the cerebellum and spinal cord. These mutations can be inherited in various patterns, including autosomal dominant, autosomal recessive, or X-linked inheritance. Genetic testing can help identify specific mutations, which is crucial for diagnosis and family planning.

Diagnosis and Management

Diagnostic Approach

Diagnosis typically involves a combination of clinical evaluation, family history assessment, and genetic testing. Neurological examinations may reveal characteristic signs of ataxia, and imaging studies like MRI can help visualize brain and spinal cord changes.
