Genes affected

DCP1B (HGNC:24451): (decapping mRNA 1B) This gene encodes a member of a family of proteins that function in removing the 5' cap from mRNAs, which is a step in regulated mRNA decay. This protein localizes to cytoplasmic foci which are the site of mRNA breakdown and turnover. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Dec 20, 2023

The c.1409G>A (p.R470Q) alteration is located in exon 7 (coding exon 7) of the DCP1B gene. This alteration results from a G to A substitution at nucleotide position 1409, causing the arginine (R) at amino acid position 470 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
