Abstract

Steroidogenic factor-1 (SF-1), also known as nuclear receptor subfamily 5 group A member 1 (NR5A1), is a member of orphan receptor subfamily and located on chromosome 9 (9q33). In 46, XY individuals with mutation of SF-1 gene, adrenal failure, testis dysgenesis, androgen synthesis defects, hypospadias and anorchia with microphallus, infertility can occur from severe to mild. We report a case of a 20-day-old male who is admitted to our clinic due to ambiguous genitalia. In this report, we describe a novel heterozygous c.814A > C (p.T272P) NR5A1 mutation in a patient with 46, XY DSD without adrenal insufficiency. We describe a novel missense mutation c.814A > C (p.T272P) in NR5A1 gene which had not previously been reported. Also this report highlights that the potential diagnostic utility of next-generation sequencing is an effective strategy versus Sanger sequencing to identify genetic mosaicism in clinical practice.
