Genes affected

DHRS4L2 (HGNC:19731): (dehydrogenase/reductase 4 like 2) This gene encodes a member of the short chain dehydrogenase reductase family. The encoded protein may be an NADPH dependent retinol oxidoreductase. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

DHRS4-AS1 (HGNC:23175): (DHRS4 antisense RNA 1)

DHRS4L1 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP7: Synonymous conserved (PhyloP=-0.294 with no splicing effect.
