Labcorp Genetics (formerly Invitae), Labcorp RCV005202658 SCV005832742 uncertain significance Intellectual disability, autosomal recessive 53 2024-11-04 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with histidine, which is basic and polar, at codon 64 of the PIGG protein (p.Leu64His). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with PIGG-related conditions. 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) has been performed 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 PIGG 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.
