Background: Congenital adrenal hyperplasia (CAH) caused by 3ß-HSD deficiency is a rare form of congenital adrenal deficiency with an autosomal recessive type of inheritance. We have previously demonstrated that a single nucleotide variant NM_000198.3:c.690G>A (P.W230X) in the homozygous state is a frequent cause of CAH among the indigenous population of North Ossetia-Alania represented by Ossetians.Aims: To stud...
