Term Name:	nuclear-transcribed mRNA catabolic process, nonsense-mediated decay
Synonyms:	mRNA breakdown, nonsense-mediated decay, mRNA catabolic process, nonsense-mediated, mRNA catabolism, nonsense-mediated, mRNA degradation, nonsense-mediated decay, nonsense-mediated mRNA decay, nuclear mRNA catabolic process, nonsense-mediated decay
Definition:	The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins.
