Genes affected

DHRS2 (HGNC:18349): (dehydrogenase/reductase 2) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) family, which has over 46,000 members. Members of this family are enzymes that metabolize many different compounds, such as steroid hormones, prostaglandins, retinoids, lipids and xenobiotics. Alternative promoter use and alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2017]

Collection Method: clinical testing

The c.44C>A (p.P15H) alteration is located in exon 2 (coding exon 1) of the DHRS2 gene. This alteration results from a C to A substitution at nucleotide position 44, causing the proline (P) at amino acid position 15 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
