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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.145C>T (p.R49C) alteration is located in exon 2 (coding exon 2) of the DCXR gene. This alteration results from a C to T substitution at nucleotide position 145, causing the arginine (R) at amino acid position 49 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
