To study the association between ADAM33 and keloid scars in the northeastern Chinese population.
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.
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).
Our data suggest that the ADAM33 polymorphisms may be associated with keloid scars in the northeastern Chinese population.
研究中国东北人群中ADAM33与瘢痕疙瘩之间的关联。
本研究共招募了283例瘢痕疙瘩患者和290名健康志愿者作为对照组。选择ADAM33的六个多态性位点（V4、T+1、T2、T1、S2和Q-1）进行基因分型。采用聚合酶链反应-限制性片段长度多态性（PCR-RFLP）方法确定基因型。
我们观察到，病例组中rs612709 A等位基因的频率显著低于对照组（22%对39.6%，P<0.0001）。我们还发现，病例组中H2（GGAAGA）单倍型的频率显著高于对照组（P=0.041）。相反，H8（GGGAGG）单倍型在对照组中比病例组更常见（P=0.022）。
我们的数据表明，ADAM33基因多态性可能与中国东北人群的瘢痕疙瘩有关。
