Genes affected

NR5A1 (HGNC:7983): (nuclear receptor subfamily 5 group A member 1) The protein encoded by this gene is a transcriptional activator involved in sex determination. The encoded protein binds DNA as a monomer. Defects in this gene are a cause of XY sex reversal with or without adrenal failure as well as adrenocortical insufficiency without ovarian defect.

ACMG classification

Verdict is Pathogenic. Variant got 13 ACMG points.

• PVS1: Start lost variant, no new inframe start found.
• PS1: Another start lost variant in NM_004959.5 (NR5A1) was described as [Pathogenic] in Lovd
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-124503393-C-T is Pathogenic according to our data. Variant chr9-124503393-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 12806.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr9-124503393-C-T is described in Lovd as [Pathogenic].
