Invitae RCV002513867 SCV003441171 pathogenic Mevalonic aciduria; Porokeratosis 3, disseminated superficial actinic type; Hyperimmunoglobulin D with periodic fever 2023-11-08 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 326 of the MVK protein (p.Gly326Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with mevalonate kinase deficiency (PMID: 11313769, 18941711, 23979089, 32060250). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 97639). 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 not expected to disrupt MVK protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic.
