PDLIM7 and nasopharyngeal carcinoma: Analysis revealed that aside from BALF2 variants, some of the known NPC‐risk variants discovered from the Southern Chinese populations, such as EBER2‐deletion (EBER‐del) [6], RPMS1_G155391A [13], and BNRF1‐V1222I [14], and variants reported to be higher in NPC, including BZLF1 Zp‐V3 variant (G‐G‐G) [15], EBNA‐1 T85A, A439T, and H418L [16], and LMP1 XhoI G169413T and 30‐bp deletions [17], are indeed common in Cluster 4 but less or uncommon in Clusters 6 and 8 (Figure 3A).
