T2D patients presented several genes that were differentially expressed compared to T1D patients, including genes of numerous zinc finger proteins and genes regulating transcription (ZNF184, ZNF576, ZNF449, ZNF594, ZNF641, ZNF100, ZNF644, ZNF189, ZNF785, ZNF436, ZNF613, among others). This evidence concerns the gene ZNF449 and type 2 diabetes mellitus.
