Association of HLA-DRB1,DQA1,DQB1 in Patients with Bullous Pemphigoid / 中华皮肤科杂志

ABSTRACT

Objective To investigate the association between HLA classⅡgenes and bullous pem-phigoid(BP).Methods HLA-DRB1,DQA1,DQB1were determined by polymerase chain reaction se-quence specific oligonucleotide probe methods in56patients with BP and150normal controls from Shanghai area.Results It was shown that HLA-DRB1*10(*1001)was linked to DQB1*0501,and its frequency in-creased significantly in BP group compared to normal controls.There was a positive correlation between DRB1*1001and mucosal involvememt as well as autoantigen BP230.HLA-DRB1*04was linked to DQB1*0302,and its frequency increased significantly in BP group compared with normal control.There was a positive correlaton between DRB1*04and autoantigen BP180.The frequency of HLA-DRB1*12(*1201,*1202)decreased in BP group compared to normal controls.Conclusions It is suggested that HLA-DRB1*1001and DRB1*04be the susceptible genes while DRB1*1201,and*1202be the protective genes of BP patients in Shanghai area.
