Test ID SEP9Z SEPTIN9 Gene, Full Gene Analysis, Varies


Ordering Guidance


Targeted testing (also called site-specific or known variants testing) is available for variants identified in the SEPTIN9 gene. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.

 

Testing for SEPTIN9 gene as part of a customized panel is available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.

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.
