| associations between hla-dqb1 high-risk alleles and type i diabetes do not depend on cytomegalovirus antibody status at onset: a case-parent study conducted in chile. | the purpose of the present study is to ascertain whether the associations between hla-dqb1*0201 and dqb1*0302 alleles and childhood diabetes depend on the presence of antibodies to human cytomegalovirus (cmv). a study of incident type i diabetes cases and parents was conducted in santiago, chile. hla-dqb1 polymorphisms were determined in 85 case-parent trios (255 subjects), while the detection of cmv was carried out only in the incident cases. as expected, hla-dqb1 polymorphisms are strongly ass ... | 2000 | 10849114 |
