Genes affected

HSD17B10 (HGNC:4800): (hydroxysteroid 17-beta dehydrogenase 10) This gene encodes 3-hydroxyacyl-CoA dehydrogenase type II, a member of the short-chain dehydrogenase/reductase superfamily. The gene product is a mitochondrial protein that catalyzes the oxidation of a wide variety of fatty acids and steroids, and is a subunit of mitochondrial ribonuclease P, which is involved in tRNA maturation. The protein has been implicated in the development of Alzheimer disease, and mutations in the gene are the cause of 17beta-hydroxysteroid dehydrogenase type 10 (HSD10) deficiency. Several alternatively spliced transcript variants have been identified, but the full-length nature of only two transcript variants has been determined. [provided by RefSeq, Aug 2014]

ACMG classification

Verdict is Pathogenic. Variant got 16 ACMG points.

• PM1: In a chain 3-hydroxyacyl-CoA dehydrogenase type-2 (size 259) in uniprot entity HCD2_HUMAN there are 20 pathogenic changes around while only 6 benign (77%) in NM_004493.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.984
• PP5: Variant X-53431513-C-T is Pathogenic according to our data. Variant chrX-53431513-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 496894.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chrX-53431513-C-T is described in Lovd as [Pathogenic].
