Genes affected
HSD3B2 (HGNC:5218): (hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 2) The protein encoded by this gene is a bifunctional enzyme that catalyzes the oxidative conversion of delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. It plays a crucial role in the biosynthesis of all classes of hormonal steroids. This gene is predominantly expressed in the adrenals and the gonads. Mutations in this gene are associated with 3-beta-hydroxysteroid dehydrogenase, type II, deficiency. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2009]

  • congenital adrenal hyperplasia due to 3-beta-hydroxysteroid dehydrogenase deficiency

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.006784588).
BP6
Variant 1-119422208-T-C is Benign according to our data. Variant chr1-119422208-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 36370.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.012 (1823/152276) while in subpopulation AFR AF = 0.0412 (1712/41550). AF 95% confidence interval is 0.0396. There are 32 homozygotes in GnomAd4. There are 834 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 32 AR gene
