A non-redundant set of CNV regions with the total length of about 36 Mb was identified, including several novel T2D susceptibility loci involving 16 protein-coding genes (Il18r1, Cyp4a3, Sult2a1, Sult2a2, Sult2al1, Nos2, Pstpip1, Ugt2b, Uxs1, RT1-A1, RT1-A3, RT1-Db1, RT1-N1, RT1-N3, RT1-O, and RT1-S2) and two microRNA genes (rno-mir-30b and rno-mir-30d). Here, UXS1 is linked to type 2 diabetes mellitus.
