We found that rs768963 polymorphism was significantly more frequent in the CI group than in the non-CI group and the T-T-G-T haplotype of C795T-T924C-G1686A-rs768963 was significantly less frequent in the CI subjects (0.238 versus 0.339; OR 0.617 [95%CI 0.444-0.856]).
However, there was a significant difference in the overall distribution of genotypes and dominant/recessive models of rs768963 between CI and control groups.
Analysis demonstrated that there were significant differences in the overall distribution of genotypes and dominant or recessive models of rs2271875 and rs768963 between the CI and the non-CI groups.
