To the best of our knowledge, this is the first study to demonstrate that 2 SNPs (TUSC7 rs1829346 and rs36080650) were correlated with dermatitis, 3 SNPs (LINC-ROR rs2027701, pR-lncRNA-1 rs73594404 and LINC-PINT rs1059698) were related to neutropaenia, 2 SNPs (MEG3 rs10132552, pR-lncRNA-1 rs73594404) and 1 SNP (LINC-PINT rs1059698) were associated with anaemia and myelosuppression in NPC patients, respectively. The gene discussed is MEG3; the disease is myelosuppression.
