Genes affected

DCXR (HGNC:18985): (dicarbonyl and L-xylulose reductase) The protein encoded by this gene acts as a homotetramer to catalyze diacetyl reductase and L-xylulose reductase reactions. The encoded protein may play a role in the uronate cycle of glucose metabolism and in the cellular osmoregulation in the proximal renal tubules. Defects in this gene are a cause of pentosuria. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2010]

Collection Method: clinical testing

The c.688A>T (p.T230S) alteration is located in exon 8 (coding exon 8) of the DCXR gene. This alteration results from a A to T substitution at nucleotide position 688, causing the threonine (T) at amino acid position 230 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
