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]

The c.157A>T (p.N53Y) alteration is located in exon 2 (coding exon 2) of the DCP2 gene. This alteration results from a A to T substitution at nucleotide position 157, causing the asparagine (N) at amino acid position 53 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
