ACYP2 and nasopharyngeal carcinoma: We used allele-specific RNA-seq datasets from 16 NPC clones (nine previously published and seven additional clones from this study - Supplementary Table 4)11,31 and compared the distribution of allelic expression ratios for the Acyp2, A2m, Bag3, Eya4 and Grik2 genes, together with eight neighbouring genes located upstream and downstream (Fig. 7a and Supplementary Fig. 6a).
