Genes affected

HSD17B3 (HGNC:5212): (hydroxysteroid 17-beta dehydrogenase 3) This isoform of 17 beta-hydroxysteroid dehydrogenase is expressed predominantly in the testis and catalyzes the conversion of androstenedione to testosterone. It preferentially uses NADP as cofactor. Deficiency can result in male pseudohermaphroditism with gynecomastia. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000368 (56/152222) while in subpopulation AMR AF = 0.00268 (41/15288). AF 95% confidence interval is 0.00203. There are 0 homozygotes in GnomAd4. There are 26 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
