Invitae RCV001042343 SCV001206020 pathogenic Charcot-Marie-Tooth Neuropathy X 2019-11-04 criteria provided, single submitter clinical testing This sequence change replaces proline with alanine at codon 87 of the GJB1 protein (p.Pro87Ala). The proline residue is highly conserved and there is a small physicochemical difference between proline and alanine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in individual(s) with X-linked Charcot-Marie-Tooth disease (PMID: 8990008, 19062535, 25802885). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 155724). This variant has been reported to have conflicting or insufficient data to determine the effect on GJB1 protein function (PMID: 9354338). For these reasons, this variant has been classified as Pathogenic.
