Genes affected

HSD3B1 (HGNC:5217): (hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1) The protein encoded by this gene is an enzyme that catalyzes the oxidative conversion of delta-5-3-beta-hydroxysteroid precursors into delta-4-ketosteroids, which leads to the production of all classes of steroid hormones. The encoded protein also catalyzes the interconversion of 3-beta-hydroxy- and 3-keto-5-alpha-androstane steroids. [provided by RefSeq, Jun 2016]

The c.359T>C (p.F120S) alteration is located in exon 4 (coding exon 3) of the HSD3B1 gene. This alteration results from a T to C substitution at nucleotide position 359, causing the phenylalanine (F) at amino acid position 120 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
