Genes affected

DHRS1 (HGNC:16445): (dehydrogenase/reductase 1) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) family. The encoded enzyme contains a conserved catalytic domain and likely functions as an oxidoreductase. Multiple alternatively spliced variants, encoding the same protein, have been identified.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.914T>C (p.I305T) alteration is located in exon 9 (coding exon 8) of the DHRS1 gene. This alteration results from a T to C substitution at nucleotide position 914, causing the isoleucine (I) at amino acid position 305 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
