Disease association HLA-DQB1
1 disease association
1.1 diabetes
1.2 celiac disease
1.3 multiple sclerosis
1.4 narcolepsy
disease association
diabetes
several alleles of hla-dqb1 associated increased risk of developing type 1 diabetes. locus has genetic name iddm1 highest genetic risk type 1 diabetes. again dqb1*0201 , dqb1*0302 alleles, particularly phenotype dqb1*0201/*0302 has high risk of late onset type 1 diabetes. risk partially shared hla-dr locus (dr3 , dr4 serotypes).
celiac disease
celiac1 genetic name dqb1, hla dqb1*0201, *0202, , *0302 encode genes mediate autoimmune coeliac disease. homozygotes of dqb1*0201 have higher risk of developing celiac disease, relative other genetic locus.
multiple sclerosis
certain hla-dqb1 alleles linked modest increased risk of multiple sclerosis.
narcolepsy
other hla-dqb1 alleles associated predisposition narcolepsy, hla-dqb1*0602, carried on 90% of patients narcolepsy-cataplexy.
