D Project Group (2006) [5].Risk genetic lociThere are a minimum of 20 regions of your genome provisionally assigned as the components predisposing to T1DM. The genes at the HLA locus on human chromosome six play a important part in assisting the immunesystem to discriminate between ‘self’ (for instance the beta cells on the pancreas) and non-self (for example bacteria and viruses). Inheriting specific HLA alleles increases the probability that immune cells will attack the body’s own beta cells, thereby predisposing to kind 1 diabetes. Inside the HLA area, the genes are dihttp://ijbsInt. J. Biol. Sci. 2013, Vol.vided into three classes: Class I genes (HLA-A, HLA-B and HLA-C), that are situated around the surface of all nucleated cells [11], encoding class I HLA antigens; Class II genes (HLA-DR, HLA-DQ and HLA-DP), which can produce class II HLA antigens which can be located exclusively on macrophages, B-lymphocytes, activated T-lymphocytes, and epithelial cells with the islets of Langerhans; Class III genes, code for complement components (C2, properdin issue B, C4A and C4B), and products involved in T-cell-mediated inflammation, such as TNF-, TNF-, and acute phase protein [12]. The main susceptibility for T1D has been mapped towards the HLA class II genes HLA-DQB1, -DQA1 and -DRB1 [13]. Each susceptible and protective DR-DQ haplotypes exist in all populations. In the early 1970s, various groups found that there is a partnership among HLA class I and T1D. Later, it was identified that lymphocyte-defined HLA-D antigens, HLA class II DR3 (HLA-DRB1*0301, DQB1*0201) and DR4 (HLA-DRB1*04, DQB1*0302) were a lot more closely linked with T1D [14], accounting for apTable 1.

Besides HLA, the insulin gene (IDDM2) on chromosome 11 [19], the CTLA4 gene at the IDDM12 susceptibility locus [20], PTPN22 lyp [21] along with other susceptibility loci are also strongly associ.
