Genes affected

DCP2 (HGNC:24452): (decapping mRNA 2) The protein encoded by this gene is a key component of an mRNA-decapping complex required for degradation of mRNAs, both in normal mRNA turnover, and in nonsense-mediated mRNA decay (NMD). It removes the 7-methyl guanine cap structure from mRNA, prior to its degradation from the 5' end. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]

Feb 22, 2023

The c.236A>C (p.Q79P) alteration is located in exon 3 (coding exon 3) of the DCP2 gene. This alteration results from a A to C substitution at nucleotide position 236, causing the glutamine (Q) at amino acid position 79 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
