NR5A1

Chr 9AD

nuclear receptor subfamily 5 group A member 1

Also known as: AD4BP, ELP, FTZ1, FTZF1, POF7, SF-1, SF1, SPGF8

NR5A1 encodes a transcriptional activator essential for sexual differentiation and formation of primary steroidogenic tissues, binding to promoter regions of steroidogenic genes including CYP11A, CYP11B, and CYP21B. Mutations cause disorders of sex development including 46XX and 46XY sex reversal, adrenocortical insufficiency, premature ovarian failure, and spermatogenic failure with autosomal dominant inheritance. The gene is highly constrained against loss-of-function variants (pLI 0.99), reflecting its critical role in gonadal and adrenal development.

Clinical SummaryNR5A1
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.99). One damaged copy is likely sufficient to cause disease.

Literature Evidence

LOFWe identified a partial NR5A1 deletion affecting exons 2 and 3, leading to NR5A1 haploinsufficiency in 1 patient presenting with female external genitalia with clitoromegaly, absence of a uterus, and mildly dysgenetic testes.PMID:21654157
