Genes affected

DCP1A (HGNC:18714): (decapping mRNA 1A) Decapping is a key step in general and regulated mRNA decay. The protein encoded by this gene is a decapping enzyme. This protein and another decapping enzyme form a decapping complex, which interacts with the nonsense-mediated decay factor hUpf1 and may be recruited to mRNAs containing premature termination codons. This protein also participates in the TGF-beta signaling pathway. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2014]

The c.793T>A (p.L265I) alteration is located in exon 7 (coding exon 7) of the DCP1A gene. This alteration results from a T to A substitution at nucleotide position 793, causing the leucine (L) at amino acid position 265 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
