KLF7 and type 2 diabetes mellitus: In their study, they genotyped 33 single nucleotide polymorphisms (SNPs) in 12 KLF genes in T2DM patients and found a direct association between an allele of the SNP site in the second intron of KLF7 and T2DM, suggesting KLF7 as a novel candidate gene for genetic susceptibility to T2DM and its role in promoting the development of diabetic cardiomyopathy.
