Useful For
Establishing a molecular diagnosis for patients with hereditary neuralgic amyotrophy
Identifying variants within SEPTIN9 known to be associated with hereditary neuralgic amyotrophy, allowing for predictive testing of at-risk family members
Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in one gene associated with hereditary neuralgic amyotrophy: SEPTIN9. See Method Description for additional details.
Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, recurrence risk assessment, familial screening, and genetic counseling for hereditary neuralgic neuropathy.
Disease States
- Hereditary neuralgic amyotrophy
