Labcorp Genetics (formerly Invitae), Labcorp RCV002011782 SCV002301644 uncertain significance Immunodeficiency 14 2023-11-27 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 548 of the PIK3CD protein (p.Arg548Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PIK3CD-related conditions. ClinVar contains an entry for this variant (Variation ID: 1510460). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PIK3CD protein function. 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.
