Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms of early-onset dystonia
  • ✓Symptoms of Parkinsonism
  • ✓Presence of abnormal movements
  • ✓Family history of Segawa syndrome
  • ✓Family history of related neurological disorders
  • ✓Assessment of genetic risk for Segawa syndrome

In plain language

What this test helps you understand

Confirms diagnosis of Segawa syndrome by identifying mutations in the TH gene. Aids in understanding genetic risk for individuals and families with a history of the disorder. Informs treatment strategies and family planning.
The TH Gene Segawa Syndrome Autosomal Recessive NGS Genetic DNA Test is a specialized diagnostic tool designed to identify genetic mutations linked to Segawa syndrome. This rare neurological disorder affects dopamine synthesis in the brain. This test utilizes advanced Next-Generation Sequencing (NGS) technology to analyze the TH gene. Understanding your genetic makeup related to this condition can significantly influence treatment options and familial health planning.

This genetic test measures specific mutations in the TH gene that are known to cause Segawa syndrome. Identifying these mutations allows healthcare providers to confirm a diagnosis and develop appropriate management strategies.

This test is recommended for individuals presenting with symptoms suggestive of Segawa syndrome, such as early-onset dystonia, Parkinsonism, or abnormal movements. It is also valuable for individuals with a family history of Segawa syndrome or related neurological disorders to assess their genetic risk.

Taking this test provides several benefits, including an accurate diagnosis, support for informed treatment decisions, insights for family planning and risk assessment, and access to genetic counseling for affected families.

Results will be interpreted by your healthcare provider, potentially with assistance from a genetic counselor, to understand the genetic factors involved and discuss implications for management and treatment.
