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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.1606G>A (p.V536I) alteration is located in exon 8 (coding exon 8) of the DCP1B gene. This alteration results from a G to A substitution at nucleotide position 1606, causing the valine (V) at amino acid position 536 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
