Labcorp Genetics (formerly Invitae), Labcorp RCV001348249 SCV001542543 likely pathogenic Mevalonic aciduria; Porokeratosis 3, disseminated superficial actinic type; Hyperimmunoglobulin D with periodic fever 2020-11-19 criteria provided, single submitter clinical testing This sequence change replaces serine with proline at codon 267 of the MVK protein (p.Ser267Pro). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and proline. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MVK protein function. This variant has been observed in individual(s) with clinical features of MVK-related condition (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency).
