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 GeneticsOct 04, 2022The c.1834G>A (p.A612T) alteration is located in exon 9 (coding exon 9) of the DCP1B gene. This alteration results from a G to A substitution at nucleotide position 1834, causing the alanine (A) at amino acid position 612 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
