CXCL12 and cervical carcinoma: The location of these SNPs in the 5′ UTR (rs17885289), second intron (rs266085), and 3′ UTR (rs266093) regions of the CXCL12 gene is consistent with several possible aetiologic mechanisms for the identified association with cervical carcinoma, including alternative splicing and regulation of CXCL12 induction [91–93].
