Labcorp Genetics (formerly Invitae), Labcorp RCV001855975 SCV002193344 uncertain significance not provided 2024-09-16 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 950 of the MYH14 protein (p.Glu950Lys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of MYH14-related conditions (PMID: 30828794). This variant is also known as c.2971G>A (p.Glu991Lys). ClinVar contains an entry for this variant (Variation ID: 626217). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt MYH14 protein function with a positive predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
