{Reference Type}: Review {Title}: NR5A1-related 46,XY partial gonadal dysgenesis: A case report and literature review. {Author}: Wei X;Li S;He Y; {Journal}: Medicine (Baltimore) {Volume}: 102 {Issue}: 52 {Year}: 2023 Dec 29 {Factor}: 1.817 {DOI}: 10.1097/MD.0000000000036725 {Abstract}: BACKGROUND: Disorders/differences of sex development (DSD) include a diverse group of congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is discordant. It involves several variant genes, and one of them is NR5A1. NR5A1 encodes a signal transduction regulator in the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal pathway, and pathogenic mutation in this gene is a cause of 46,XY DSD.
METHODS: A 12-year-old individual raised as a girl was admitted to the hospital due to hirsutism and a deep voice that began at 11 years old. The individual exhibited testicular hypoplasia, clitoral hypertrophy, and female external genitalia.
METHODS: The patient was diagnosed 46,XY partial gonadal dysgenesis. The cytogenetics revealed a 46,XY karyotype and DNA sequencing shown a variant in NR5A1. Pelvic magnetic resonance imaging showed absence of uterus and ovaries. The abdominopelvic ultrasound revealed bilateral testicle in bilateral groin. Pathology confirmed testes dysgenesis.
METHODS: The patient underwent bilateral orchiectomy at age 12 years and was given a feminizing hormonal treatment of 0.5 mg/day of estradiol valerate tablets.
RESULTS: The patient recovered well after surgery and hormonal treatment and had a regression in hirsutism and clitoromegaly.
CONCLUSIONS: 46,XY DSD is a rare disease that the development of chromosomal, gonadal, or anatomical sex is discordant, when diagnosed 46,XY DSD, the identification of an NR5A1 variant should be considered.
