Labcorp Genetics (formerly Invitae), Labcorp	RCV000798174	SCV000937775	pathogenic	Charcot-Marie-Tooth disease type 4A	2018-12-13	criteria provided, single submitter	clinical testing	This sequence change replaces threonine with proline at codon 157 of the GDAP1 protein (p.Thr157Pro). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual affected with Charcot-Marie-Tooth disease (PMID: 15805163), which is consistent with an autosomal dominant pattern of inheritance. ClinVar contains an entry for this variant (Variation ID: 4199). This variant has been reported to affect GDAP1 protein function via a dominant-negative or gain-of-function mechanism (PMID: 19782751, 23628762, 21890626, 18021315, 28220846). For these reasons, this variant has been classified as Pathogenic.
