Context Cytochrome P450 side-chain cleavage enzyme (CYP11A1) catalyses the first and rate-limiting step of steroidogenesis, the conversion of cholesterol to pregnenolone. CYP11A1 deficiency is commonly associated with adrenal insufficiency, and in 46

Background Congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder due to mutation in the CYP21A2 gene. Objective To elucidate the genetic basis of 21-hydroxylase-deficient CAH in Hong Kong

BACKGROUND 5α-Reductase 2 deficiency (5ARD) is a known cause of 46,XY disorders of sex development (DSD). Traditionally, the diagnosis relies on dihydrotestosterone (DHT) measurement, but the results are often equivocal, potentially leading to misdi

Background Deficiency in any one of the steroidogenic enzymes may result in congenital adrenal hyperplasia (CAH) and disorders of sex development (DSD). Urinary steroid profiling (USP) can quantify metabolites of all relevant steroids simultaneously

To the Editor: The steroid metabolic disorder 21-hydroxylase deficiency (21OHD)1 is increasingly being included in blood spot–based newborn-screening programs. Screening most commonly relies on 17-hydroxyprogesterone immunoassay, but it gives a hig
