Abstract
OBJECTIVE
To explore the association between polymorphism of the human leukocyte antigen G (HLA-G) and susceptibility of esophageal carcinoma (EC) in Kazakh and Han nationality in Xinjiang.
METHODS
The 14 bp deletion/insertion (rs16375) and 0105N (rs41557518) of HLA-G genotyping were determined by PCR and PCR-RFLP, respectively in 239 patients and 467 controls.
RESULTS
There was a 2.69-fold (P(c) = 0.04, 95% CI: 1.30-5.55) increased risk of developing EC in individuals with the -14 bp/-14 bp genotype (rs16375) compared with those carrying +14 bp/+14 bp genotype in Kazakh after Bonferroni correction, there was no association of 0105N (rs41557518) both in Kazak and Han population. And there was a 2.82-fold (P(c) = 0.04, 95% CI: 1.32-6.04) increased risk of developing EC in individuals with -14 bp/-14 bp and C/C genotypes compared with those who had +14 bp/+14 bp and C/C genotypes in Kazakh.
CONCLUSIONS
The study demonstrates that EC is associated with polymorphism of HLA-G14 bp in Chinese Kazak population. The 14 bp deletion/insertion of HLA-G gene may play a role in EC susceptibility of Kazakh.
