Genes affected

HSD17B8 (HGNC:3554): (hydroxysteroid 17-beta dehydrogenase 8) In mice, the Ke6 protein is a 17-beta-hydroxysteroid dehydrogenase that can regulate the concentration of biologically active estrogens and androgens. It is preferentially an oxidative enzyme and inactivates estradiol, testosterone, and dihydrotestosterone. However, the enzyme has some reductive activity and can synthesize estradiol from estrone. The protein encoded by this gene is similar to Ke6 and is a member of the short-chain dehydrogenase superfamily. An alternatively spliced transcript of this gene has been detected, but the full-length nature of this variant has not been determined. [provided by RefSeq, Jul 2008]

The c.391A>G (p.T131A) alteration is located in exon 4 (coding exon 4) of the HSD17B8 gene. This alteration results from a A to G substitution at nucleotide position 391, causing the threonine (T) at amino acid position 131 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
