| hla class ii genotypic frequencies in atopic asthma: association of drb1*01-dqb1*0501 genotype with artemisia vulgaris allergic asthma. | different human leukocyte antigen (hla) class ii alleles have been associated with the development of atopic asthma. to determine whether hla class ii alleles are associated with atopic asthma in a population from southeast spain (murcia region), 213 atopic asthmatic patients and 150 controls were selected for hla typing. significant association of the drb1*01 and dqb1*0501 alleles was found in artemisia vulgaris allergic patients (p(c) = 0.00052 and p(c) = 0.00023, respectively). no significant ... | 2003 | 12878360 |
