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]

Ambry Genetics

Sep 15, 2021

The c.481G>A (p.V161I) alteration is located in exon 6 (coding exon 6) of the HSD17B3 gene. This alteration results from a G to A substitution at nucleotide position 481, causing the valine (V) at amino acid position 161 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
