RCV003007337 | SCV003305467 | uncertain significance | Megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome 1 | 2022-08-23 | 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 not expected to disrupt PIK3R2 protein function. This variant has not been reported in the literature in individuals affected with PIK3R2-related conditions. 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 sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 276 of the PIK3R2 protein (p.Ser276Asn). |
| Ambry Genetics | RCV003170847 | SCV003871768 | likely benign | Inborn genetic diseases | 2023-02-15 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
