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]

ENSG00000293080 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.857 is higher than 0.05.
