Labcorp Genetics (formerly Invitae), Labcorp RCV001994033 SCV002257794 likely pathogenic Cranioectodermal dysplasia 2; Short-rib thoracic dysplasia 7 with or without polydactyly 2021-07-15 criteria provided, single submitter clinical testing This sequence change replaces serine with arginine at codon 168 of the WDR35 protein (p.Ser168Arg). The serine residue is highly conserved and there is a moderate physicochemical difference between serine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of a WDR35-related condition (PMID: 22486404; Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
