Alleles of two novel SNPs (c.192 + 353 C>A, OR = 0.095, 95% CI: 0.013-0.714, P = 0.022; c.192 + 463 G>A, OR = 0.090, 95% CI: 0.012-0.675, P = 0.019) and SNP rs3729843 (OR = 1.889, 95% CI: 1.252-2.852; P = 0.002) were significantly correlated with DCM.
In the TNNT2 gene, there was a significant association between DCM and genotype for the tagging SNPs rs3729547 (χ(2) = 6.63, P = 0.036, OR = 0.650, and 95% CI = 0.453-0.934) and rs3729843 (χ(2) = 9.787, P = 0.008, OR = 1.912, and 95% CI = 1.265-2.890) in the Chinese Han population.
