    Abstract:
    OBJECTIVE: To study the association between ADAM33 and keloid scars in the northeastern Chinese population. METHODS: A total of 283 keloid scar patients and a control group of 290 healthy volunteers were recruited for this study. Six polymorphic loci (V4, T+1, T2, T1, S2 and Q-1 ) of ADAM33 were selected for genotyping. Genotypes were determined by using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. RESULTS: We observed the frequency of the rs612709 A allele exhibited a significantly decreased frequency in cases than in controls(22 vs.39.6%, P<0.0001) We also found that the frequencies of H2 (GGAAGA) haplotypes was significantly higher in the case group than in the control group (P= 0.041). In contrast, the haplotype H8 (GGGAGG) was more common in the control group than in the case group (P=0.022). CONCLUSIONS: Our data suggest that the ADAM33 polymorphisms may be associated with keloid scars in the northeastern Chinese population.
