Hereditary Neuropathy Panel

Concurrent analysis of multiple genes associated with inherited neuropathies including Charcot-Marie-Tooth neuropathies.

NY Approved

Test Overview

Clinical Utility

  • Molecular confirmation of a clinical diagnosis
  • To assist with decisions about treatment and management of individuals with neuropathy
