Labcorp Genetics (formerly Invitae), Labcorp RCV000821009 SCV000961748 uncertain significance Megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome 1 2022-12-02 criteria provided, single submitter clinical testing 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. 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 PIK3R2 protein function. ClinVar contains an entry for this variant (Variation ID: 663183). This variant has not been reported in the literature in individuals affected with PIK3R2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 375 of the PIK3R2 protein (p.Asn375Ser).
