Distances of NMD-QTLs to boundaries of exons, introns, and stop codons. a Distances to exon boundaries for variants located on an exon interval. The comparison is made between pNMD-QTLs and eQTLs. b Distances to intron boundaries for variants located on an intron interval. The comparison is made between pNMD-QTLs and eQTLs. Similar results for dNMD-QTLs can be found in Additional file 1: Fig. S5. c Distances of exonic NMD-QTLs to PTCs of NMD-targeted transcripts, and to regular stop codons of non-NMD transcripts. Only exonic positions are counted in the distance calculation. d Distance between genic NMD-QTLs and the stop codons. Both exonic and intronic positions are counted in the distance calculation. Note that the distance between an NMD-QTL (or an eQTL) and each transcript isoform’s PTC (or regular stop codon) was calculated separately. All these distances are shown here
