OverviewNCBI Gene
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]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads HSD17B6 as an antibody target. Whether an autoantibody or antibody against HSD17B6 could matter depends on whether native HSD17B6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
HSD17B6 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label HSD17B6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
