RCV002305809 | SCV002599411 | uncertain significance | Anemia, nonspherocytic hemolytic, due to G6PD deficiency | 2022-08-12 | criteria provided, single submitter | curation | Normal activity when expressed in S. cerevisiae (BS3_M). Located in substrate binding site (PM1). Below expected carrier frequency in gnomAD (PM2). Post_P 0.325 (odds of pathogenicity 4.33, Prior_P 0.1). |
Invitae | RCV002305809 | SCV004299713 | likely pathogenic | Anemia, nonspherocytic hemolytic, due to G6PD deficiency | 2022-12-28 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 199 of the G6PD protein (p.Ile199Val). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on G6PD function (PMID: 16193512). 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 G6PD protein function. ClinVar contains an entry for this variant (Variation ID: 1722699). This missense change has been observed in individuals with glucose-6-phosphate dehydrogenase deficiency (PMID: 18056001, 25536053). This variant is present in population databases (rs781865768, gnomAD 0.01%). |
