RCV001000724 | SCV001157769 | pathogenic | not specified | 2018-07-24 | criteria provided, single submitter | clinical testing | The G6PD c.1465C>T; p.Pro489Ser variant is reported in the literature in at least one individual affected with severe G6PD deficiency and anemia (Minucci 2008). In this paper, the male patient had undetectable G6PD activity, and the patient's mother was negative for the variant, suggesting a de novo mutation (Minucci 2008). This variant is absent from general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database), indicating it is not a common polymorphism. Additionally, another variant at this codon (c.1466C>T; p.Pro489Leu) has been reported in at least one individual with severe G6PD and is considered a class I variant (Vulliamy 1997). The proline at codon 489 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that the p.Pro489Ser variant is deleterious. Based on available information, this variant is considered to be pathogenic. References: Minucci A et al.

RCV002305556 | SCV002599399 | pathogenic | Anemia, nonspherocytic hemolytic, due to G6PD deficiency | 2022-08-12 | criteria provided, single submitter | curation | Variant found in hemizygote with deficiency with CNSHA (PP4). No detectable activity in red blood cells (PS3). Not found in mother of hemizygote, so assumed de novo (PM6). Within NADP structural site (PM1). Predicted to be deleterious by SIFT and PolyPhen (PP3). Not found in gnomAD (PM2). Post_P 0.999 (odds of pathogenicity 6568, Prior_P 0.1). |
