BACKGROUND: Celiac disease is an enteropathy characterized by gluten sensitivity and broad clinical aspect. Has a multifactorial cause and depends on genetic, immunological and environmental factors for its development. The genetic influence is given mostly by the human leukocyte antigens HLA DQ2 and DQ8. AIM: To evaluate the prevalence of human leukocyte antigens DQ2 and DQ8 in three different groups: patients with celiac disease, first-degree relatives and the general population. METHOD: Retrospective analysis that evaluated serologic and endoscopic data of 74 patients with celiac disease and 109 non-celiac, which were subdivided into two subgroups: non-celiac who had first-degree relatives with celiac and non-celiac who did not. All patients underwent laboratory examination for screening genetic sensitivity given by HLA DQ2 and HLA DQ8 by. RESULTS: The presence of HLA DQ2 and DQ8 was identified in 98,4% of 74 celiac patients, of which 79,7% had only HLA DQ2; 8,1% had only HLA DQ8 and 10,8% had both antigens histocompatibility. In the group of relatives of celiac patients, were included 29 patients; among them, 89,6% had HLA DQ2 and/or DQ8; 76% only the HLA DQ2, 10,3% only HLA DQ8 and 3,4% presented both human leukocyte antigens (HLA). CONCLUSION: HLA DQ2/DQ8 was present in 98,4% of celiac patients; 89,6% relatives of celiac family and in 55,4% of people from the general population without family celiac.
