The Venn diagram indicated that there was a high number of transcripts which were uniquely expressed in the groups of individuals with pre-DM (n = 794) or T2DM (n = 1296), whereas patients with T1DM exhibited only 5 uniquely expressed genes (SSU72, RPL41, RPL11, CEACAM1 and MYH9) (Fig 2D). This evidence concerns the gene CEACAM1 and type 1 diabetes mellitus.
