A Novel Variant in NR5A1 Presenting as 46,XY Difference of Sex Development
Differences of sex development (DSDs) are a spectrum of congenital clinical conditions involving the development of gonadal, chromosomal, and anatomical sex. The physical presentation provides incomplete clues because underlying etiologies may present with similar findings. We describe an 8-year-old...

description | Differences of sex development (DSDs) are a spectrum of congenital clinical conditions involving the development of gonadal, chromosomal, and anatomical sex. The physical presentation provides incomplete clues because underlying etiologies may present with similar findings. We describe an 8-year-old boy from the Dominican Republic originally diagnosed with congenital adrenal hyperplasia (CAH). He was prescribed oral hydrocortisone and fludrocortisone, with irregular adherence. During infancy, he had human chorionic gonadotropin injections to stimulate phallic growth. After migrating to the United States, medications became depleted but without adrenal crisis. Laboratory testing with high-dose adrenocorticotropin stimulation study ruled out CAH. Careful examination noted an underdeveloped bifid scrotum, bilaterally undescended testicles, a 2-cm phallus, severe penoscrotal hypospadias, and chordee. Subsequently, he had a 2-stage bilateral orchiopexy and surgical repair of penoscrotal hypospadias and chordee. Genetic testing for 46,XY DSD revealed a novel, dominant, heterozygous, likely pathogenic variant (c.102 + 1G > C) in the NR5A1 gene associated with severe phenotype of undervirilized male. This case illustrates the crucial role of molecular genetic testing for the diagnosis of 46,XY DSDs and a novel NR5A1 gene variant. |
