Its specific etiology is not yet known its frequency varies in different racial and ethnic subgroups and is often associated with a strong familial, likely genetic predisposition. It was denoted that type2 DM was associated with certain HLA class II alleles were analyzed for their genotyping by Polymerase Chain Reaction-Sequences Specific Olegionucleotide (PCR-SSO) technique. The present study revealed that diabetic patients were positively associated with HLA-DQB1 0201 (83% vs. 5.0%) which is the most prevalent in patients followed by DRB1 1137 (46.7% vs. 0.0%); DRB1 0401 (41.7% vs. 2.5%),and DRB1 1306(15% vs.0.0%) while HLA,A 0201;B 3559;Cw 0410 and DQB1 0501 is negatively associated in type 2DM in comparison to healthy control groups. This study has shown that there is no significant association between FBS,HbA1c,serum insulin,HOMA2 -function , HOMA2-IR ,serum adiponectin ,serum adenosine deaminase and HLA alleles .
