FISH Analysis - Hereditary Neuropathy with Liability to Pressure Palsies HNPP \| Hereditary Pressure Sensitive Neuropathy \| Tomaculous Neuropathy
Test Information:	Confirmation of Clinical Diagnosis, Carrier Testing
Test Details
Test Code:	8467
Special Notes:	For initial screening we recommend CMA - HR (#8655). The majority (>98%) of CMT1A cases are caused by a DNA duplication of a 1.5 Mb region on 17p12 containing the PMP22 gene (test #8462). The reciprocal product of the CMT1A duplication is a 1.5 Mb deletion that causes hereditary neuropathy with liability to pressure palsies (HNPP). Approximately 80% of patients with HNPP will have a deletion detectable by FISH.
