: Hereditary Sensory and Autonomic Neuropathy Multi-Gene Panel, Blood

: What This Test Looks At

: Hereditary sensory and autonomic neuropathies (HSAN) are a group of rare inherited conditions that affect the nerves carrying sensation and controlling automatic body functions. This multi-gene panel examines several genes at once to look for variants that may cause these disorders.

: Why It May Be Ordered

: A healthcare provider may order this panel when a person has symptoms suggesting an inherited nerve disorder, such as reduced pain or temperature sensation, autonomic symptoms, or a family history of similar problems. Genetic testing can help clarify the cause and guide family discussions.

: How the Sample Is Collected

: The test is performed on a blood sample collected in a standard draw. No special preparation is usually required, though your provider will give specific instructions if needed.

: Understanding Possible Results

: Results may identify a genetic variant that explains symptoms, a variant of uncertain significance whose effect is unclear, or no relevant variant. Because interpretation depends on the specific genes and variants examined, results should always be reviewed with a genetics professional or your care team.
