Genes affected

H6PD (HGNC:4795): (hexose-6-phosphate dehydrogenase/glucose 1-dehydrogenase) There are 2 forms of glucose-6-phosphate dehydrogenase. G form is X-linked and H form, encoded by this gene, is autosomally linked. This H form shows activity with other hexose-6-phosphates, especially galactose-6-phosphate, whereas the G form is specific for glucose-6-phosphate. Both forms are present in most tissues, but H form is not found in red cells. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-9262273-G-A is Pathogenic according to our data. Variant chr1-9262273-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 31584.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).. Strength limited to SUPPORTING due to the PP5.
• BP7: Synonymous conserved (PhyloP=0.19 with no splicing effect.
