HSD17B10

MIM.300256 Xp11.2

HSD17B10 gene code for HADH2 (3-hydroxyacyl-CoA dehydrogenase type II) or endoplasmic reticulum-associated amyloid-beta binding protein (ERAB).

The HSD17B10 gene encodes 17-beta-hydroxysteroid dehydrogenase X (17-beta-HSD10) (EC 1.1.1.178), also known as SCHAD, a member of the short-chain dehydrogenase/reductase superfamily.

It is a mitochondrial enzyme that acts on a wide spectrum of substrates, including steroids, alcohols, and fatty acids, with a preference for short-chain methyl-branched acyl-CoAs.

Pathology

- germline mutations in the HADH2 gene in

  • 2-methyl-3-hydroxybutyryl-CoA dehydrogenase (MHBD) deficiency (inborn error of isoleucine degradation)
  • X-linked mental retardation with choreoathetosis, and abnormal behavior (MRXS10). (#17236142#)

- submicroscopic duplications of the hydroxysteroid dehydrogenase HSD17B10 are associated with mental retardation. (#18252223#)
