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]

The c.929G>A (p.R310K) alteration is located in exon 11 (coding exon 11) of the HSD17B3 gene. This alteration results from a G to A substitution at nucleotide position 929, causing the arginine (R) at amino acid position 310 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
