Charcot–Marie–Tooth disease (CMT) constitutes a large group of genetically heterogeneous disorders. Autosomal recessive forms of CMT are less common in the general population but account for the vast majority of CMT phenotypes in communities with a high prevalence of consanguinity. The c.692C>T (p.Pro231Leu) variant in exon 5 of the GDAP1 gene is the most frequent pathogenic variant found in the Old Order Amish population and is specifically analyzed in this targeted test.
