N2 - To further evaluate the nature of the HLA association with psoriasis, HLA haplotypes of 60 patients with type 1 (early onset, positive family history) and 30 patients with type II (late onset, no family history) psoriasis were investigated by polymerase chain reaction sequence-specific oligonucleotide hybridization (HLA class II) and serology (HLA class I). Ethnically matched blood donors (146) served as controls. In type I, but not type II psoriasis, the Caucasian HLA extended haplotype (EH) Cw6-B57-DRB1*0701-DQA1*0201-DQB1*0303 named according to the B allele EH-57.1 was highly significantly overrepresented (p cor= 0.00021). This particular EH was present in 35% of type I psoriatics but only 2% of controls. EH-57.1+ individuals therefore carry a 26 times higher risk of developing type I psoriasis than individuals who are EH-57.1-negative Further analysis of individual HLA alleles revealed that within EH-57.1, HLA class I antigens (Cw6-B57) were associated to a much higher extent with type I psoriasis than the HLA class II alleles (DRB1*0701-DQA1*0201-DQB1* 0303). Pedigree analysis of three multiply affected families over three generations revealed a cosegregation of disease with EH-57.1. These results strongly suggest that a gene for familial psoriasis is associated with the class I side of the extended haplotype Cw6-B57-DRB1*0701-DQA1*0201-DQB1*0303.
