ABSTRACT

Objective To investigate the association of human leukocytes antigen(HLA)-DR/DQ with oral lichen planus(OLP) in the area of Yangtze River Delta. Methods HLA-DRB1 and DQB1 genotyping of 44 unrelated OLP patients and 150 normal controls were performed by polymerase chain reaction-sequence specific primers(PCR-SSP) method.The data were compared between the OLP group and normal controls,and between different types of OLP patients. Results The frequency of HLA-DRB1*09 and HLA-DRB1*07 alleles were significantly higher in OLP group than those in normal controls(56.8% vs 31.3% and 27.3% vs 13.3%,P
