BMP4 and type 2 diabetes mellitus: We found that BMP4 rs8014363 showed nominal association towards type 2 diabetes, with the T allele conferring a high risk of type 2 diabetes (OR = 1.108, 95%CI 0.999–1.229, P = 0.051for allele; OR = 1.110, 95%CI 1.000–1.231, P = 0.050 for genotype), but it was no longer statistically significant after adjusting for multiple testing (empirical P = 0.3689for allele based on 10,000 permutations).
