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). The gene discussed is CEACAM1; the disease is type 2 diabetes mellitus.
