Genes affected

HSD17B6 (HGNC:23316): (hydroxysteroid 17-beta dehydrogenase 6) The protein encoded by this gene has both oxidoreductase and epimerase activities and is involved in androgen catabolism. The oxidoreductase activity can convert 3 alpha-adiol to dihydrotestosterone, while the epimerase activity can convert androsterone to epi-androsterone. Both reactions use NAD+ as the preferred cofactor. This gene is a member of the retinol dehydrogenase family. [provided by RefSeq, Aug 2013]

Collection Method: clinical testing

The c.116C>T (p.S39L) alteration is located in exon 2 (coding exon 1) of the HSD17B6 gene. This alteration results from a C to T substitution at nucleotide position 116, causing the serine (S) at amino acid position 39 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
