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]

The DCXR c.583delC variant is predicted to result in a frameshift and premature protein termination (p.His195Thrfs*7). This variant has been reported in the homozygous or compound heterozygous state in individuals with biochemically confirmed pentosuria (Pierce et al. 2011. PubMed ID: 22042873). This variant is reported in 2.1% of alleles in individuals of Ashkenazi Jewish descent in gnomAD, which is consistent with high reported frequency of this trait in individuals of Ashkenazi Jewish descent (Pierce et al. 2011. PubMed ID: 22042873). This variant is interpreted as pathogenic. Of note, pentosuria is characterized by increased urinary excretion of L-xyluloseconsidered and is considered a benign trait (OMIM: #260800; Pierce et al. 2011. PubMed ID: 22042873). -
