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.

Ambry Genetics

Feb 02, 2022

The c.767C>T (p.T256I) alteration is located in exon 4 (coding exon 3) of the DXO gene. This alteration results from a C to T substitution at nucleotide position 767, causing the threonine (T) at amino acid position 256 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
