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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.646A>G (p.M216V) alteration is located in exon 4 (coding exon 3) of the HSD17B6 gene. This alteration results from a A to G substitution at nucleotide position 646, causing the methionine (M) at amino acid position 216 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
