Test ID: NPPAN    
Peripheral Neuropathy Genetic Panels, Next-Generation Sequencing (NGS), Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of inherited peripheral neuropathies associated with known causal genes


Serving as a second-tier test for patients in whom previous targeted gene variant analyses for specific inherited peripheral neuropathy-related genes were negative


Identifying variants within genes known to be associated with inherited peripheral neuropathy, allowing for predictive testing of at-risk family members

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This ordered service includes the option for one of several peripheral neuropathy related panel tests to be performed. The specific peripheral neuropathy panel requested must be provided in order to perform this test. Testing options include the following:


-Hereditary Motor Neuropathy Panel (23 genes)

-Hereditary Sensory Neuropathy Panel (18 genes)

-Metabolic or Syndromic Neuropathies (74 genes)

-Motor and Sensory Neuropathy Panel (82 genes)

-Peripheral Neuropathy Expanded Panel (193 genes)

-SEPT9 Gene, Full Gene Analysis (1 gene)

-Spastic Paraplegia Neuropathy Panel (41 genes)

-Custom Gene Panel (https://orders.mayocliniclabs.com/en/tools/gene_panels/)

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes the option for either one of several predefined panel tests or the option to create a custom gene panel. Pricing for the Custom Gene Panel will be based on the number of genes selected (1, 2-4, 5-14, 15-49, 50-100, and 101-500). See Custom Gene Panel Ordering in Special Instructions.
