Genes affected

DXO (HGNC:2992): (decapping exoribonuclease) This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. The function of its protein product is unknown, but its ubiquitous expression and conservation in both simple and complex eukaryotes suggests that this may be a housekeeping gene.

The c.956G>A (p.R319H) alteration is located in exon 6 (coding exon 5) of the DXO gene. This alteration results from a G to A substitution at nucleotide position 956, causing the arginine (R) at amino acid position 319 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
