Genes affected
G6PD (HGNC:4057): (glucose-6-phosphate dehydrogenase) This gene encodes glucose-6-phosphate dehydrogenase. This protein is a cytosolic enzyme encoded by a housekeeping X-linked gene whose main function is to produce NADPH, a key electron donor in the defense against oxidizing agents and in reductive biosynthetic reactions. G6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. G6PD deficiency may cause neonatal jaundice, acute hemolysis, or severe chronic non-spherocytic hemolytic anemia. Two transcript variants encoding different isoforms have been found for this gene.

Anemia, nonspherocytic hemolytic, due to G6PD deficiency Uncertain:1
Uncertain significance, criteria provided, single submittercurationDunham Lab, University of WashingtonAug 12, 2022Variant found in hemizygote with deficiency and anemia (PP4). Decreased activity in red blood cells (8-23%) (PS3). Predicted to alter mRNA secondary structure and alter miRNA binding sites (PP3). Individuals with variant on 1311C>T/1365-13T>C haplotype have deficiency, some with anemia; this haplotype alone was found to have decreased G6PD activity (10-60%) (BP5). Frequency of 32.1% gnomAD2 and 35.9% gnomAD3 (BA1). Reported as benign by ARUP Laboratories and Invitae (BP6). -
