ABSTRACT
OBJECTIVE: To study the polymorphism of HLA-DM gene in Cantonese patients with condyloma acuminata(CA) and determine the susceptible genetic factors of CA. METHODS: DMA and DMB typing was performed in 98 Cantonese patients with CA and 93 healthy controls using restriction fragment length polymorphism method. RESULTS: The gene frequencies of DMA*0101 and DMB*0101 were significantly higher in the patients than in the controls (P<0.05 and P<0.01, respectively), and gene frequency of DMA*0102 was lower in patients than in the controls (P<0.01). Genotype frequencies of HLA-DM showed no significant difference between CA patients and the controls (P>0.05). CONCLUSION: DMA*0101 and DMB*0101 alleles may be the susceptibility genes or closely linked to the susceptibility gene in Cantonese patients with CA.
