A new extended haplotype Cw*0602-B57-DRB1+0701-DQA1*0201-DQB1+0201 associated with psoriasis in the Croatian population
In this study, we have analysed the distribution of HLA class II alleles and the extended haplotype HLA-Cw-B-DRB1-DQA1-DQB1 in Croatian patients with type I and type II psoriasis by hybridization with specific oligonucleotide probes. Type I psoriasis showed a significant association with the DRB1*0701 [P < 0.00001 ; relative risk (RR) = 5.83], DQA1*0201 (P < 0.00001 ; RR = 6.12), DQB1*0201 (P = 0.0006 ; RR = 3.29) and DQB1*0303 alleles (P = 0.0008 ; RR = 7.51). A negative correlation with type I disease was observed for the DQA1*0102 allele (P = 0.002 ; RR = 0.26). Type II psoriasis did not show any association with any class II alleles. The extended haplotype HLA-Cw*0602-B57-DRB1*0701-DQA1*0201-DQB1*0201 was present at a significantly higher frequency in type I patients (P < 0.00001 ; RR = 7.72). However, this haplotype was not detected at all in patients with type II psoriasis. In conclusion, the extended haplotype HLA-Cw*0602-B57-DRB1*0701-DQA1*0201-DQB1*0201 is a risk haplotype for type I disease in the Croatian population. This particular haplotype has not been reported previously in association with psoriasis in any other ethnic groups.
