Polymorphism of HLA-DQB1 promoter region in Hans IDDM patients and normal controls have been identified by PCR, PCR/SSCP and PCR/sequencing methods.No differences were found in y and s box between patients and controls carrying different allele as well as in different ethnic groups. There are two different sequences in x box,but CCTAGAGACAGATT sequence locates frequently on the haplotype with DQB1.0302 allele. Polymorphism between transcription point and y box (at position －44～-46 and －59～-61) might be associated with the genetic susceptibility to IDDM. Additionally,a new single base mutant (CACC→CAC A ) was found at position －131 and －128 in two patients carrying DQB1.0601 allele.

结果显示携带不同等位基因的患者与对照者DQB1 5'-调控区y、s box核苷酸序列相同，且与白种人基因结构一致；y box核苷酸序列存在二种结构，CCTAGAGACAGATT序列常常与DQB1.0302等位基因在同一单倍型；转录起始位点至y box间-44至-61位存在多态性，-59至-61位AAG等位基因可能与1-型糖尿病易感相关联；在2例携带DQB1.0601等位基因患者的-131至-128位间发现CACC→ACA A单个碱基取代突变。
