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]

Collection Method: clinical testing

The c.217G>A (p.V73M) alteration is located in exon 2 (coding exon 2) of the DHRS4L2 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the valine (V) at amino acid position 73 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
