NMD_transcript NMD_polymorphic_pseudogene_transcript Term added as part of collaboration with Gencode, adding biotypes used in annotation. nonsense_mediated_decay_polymorphic_pseudogene SO:0002118 sequence kareneilbeck A polymorphic pseudogene transcript that contains a CDS but has one or more splice junctions >50bp downstream of stop codon. Premature stop codon is not introduced, directly or indirectly, as a result of the variation i.e. must be present in both protein_coding and pseudogenic alleles. 2016-07-18T14:28:02Z NMD polymorphic pseudogene transcript
