Genes affected

DHRS7 (HGNC:21524): (dehydrogenase/reductase 7) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) family, which has over 46,000 members. Members in this family are enzymes that metabolize many different compounds, such as steroid hormones, prostaglandins, retinoids, lipids and xenobiotics. [provided by RefSeq, Apr 2016]

Collection Method: clinical testing

The c.803G>A (p.R268H) alteration is located in exon 6 (coding exon 6) of the DHRS7 gene. This alteration results from a G to A substitution at nucleotide position 803, causing the arginine (R) at amino acid position 268 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
