Invitae RCV001220495 SCV001392488 pathogenic Charcot-Marie-Tooth disease, type I 2023-10-03 criteria provided, single submitter clinical testing This variant, c.431_433del, is a complex sequence change that results in the deletion of 2 and insertion of 1 amino acid(s) in the MPZ protein (p.Leu144_Tyr145delinsHis). This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with clinical features of MPZ-related conditions (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 949104). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
