The role of ABCB1 single nucleotide polymorphisms (SNPs) in the development of Crohn's disease (CD) remains unclear. Due to inconsistent results of several European population-based studies and limited information on populations from Poland and Bosnia and Herzegovina (B&H), we conducted a preliminary association study of two main ABCB1 SNPs and CD. ABCB1 3435C>T and 2677G>T/A SNPs were analyzed in Polish and Bosnian patients with CD (n = 85 and n = 30, respectively) and controls (n = 82 and n = 30, respectively) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for 3435C>T and allele-specific PCR for 2677G>A/T SNP. A deviation from Hardy-Weinberg equilibrium was found for both SNPs in Polish patients with CD, and for 2677G>A/T in Polish control group. The allele and genotype frequencies of the two ABCB1 SNPs were not significantly different between the CD patients and controls in both populations (p > 0.05). Similarly, the genotype distribution of 3435C>T and 2677G>T/A SNPs was not significantly different between Polish and Bosnian patients with CD (p > 0.05). At least one mutated ABCB1 allele was carried by 97.7% of Polish and 90.0% of Bosnian patients with CD. No association was found between the ABCB1 SNPs and CD in the two populations. In conclusion, the two ABCB1 SNPs may not contribute to CD susceptibility in the populations of Poland and B&H. Further studies with larger samples in both populations are warranted.

波兰和波斯尼亚克罗恩病患者的ABCB1 3435C> T和2677G> T / A多态性-初步报告。

尚不清楚ABCB1单核苷酸多态性(SNP)在克罗恩病(CD)的发展中的作用。由于一些基于欧洲人口的研究结果不一致,并且有关波兰和波斯尼亚和黑塞哥维那(B&H)的人口信息有限,我们对两个主要的ABCB1 SNP和CD进行了初步关联研究。使用聚合酶链反应限制技术分析波兰和波斯尼亚CD患者(分别为n = 85和n = 30)和对照组(分别为n = 82和n = 30)的ABCB1 3435C> T和2677G> T / A SNP。 3435C> T的片段长度多态性(PCR-RFLP)和2677G> A / T SNP的等位基因特异性PCR。在波兰患有CD的患者中,两个SNPs均被发现偏离Hardy-Weinberg平衡,在波兰对照组中,发现2677G> A / T。在两个人群中,CD患者和对照组之间,两个ABCB1 SNP的等位基因和基因型频率没有显着差异(p> 0.05)。同样,波兰和波斯尼亚患有CD的患者中3435C> T和2677G> T / A SNP的基因型分布也无显着差异(p> 0.05)。97.7%的波兰人和90.0%的波斯尼亚CD患者携带至少一个突变的ABCB1等位基因。在这两个人群中未发现ABCB1 SNP与CD之间存在关联。总之,两个ABCB1 SNP可能对波兰和B&H人群的CD易感性没有影响。有必要对两个人群中的较大样本进行进一步研究。波兰和波斯尼亚患有CD的患者中3435C> T和2677G> T / A SNP的基因型分布无显着差异(p> 0.05)。97.7%的波兰人和90.0%的波斯尼亚CD患者携带至少一个突变的ABCB1等位基因。在这两个人群中未发现ABCB1 SNP与CD之间存在关联。总之,两个ABCB1 SNP可能对波兰和B&H人群的CD易感性没有影响。有必要对两个人群中的较大样本进行进一步研究。波兰和波斯尼亚患有CD的患者中3435C> T和2677G> T / A SNP的基因型分布无显着差异(p> 0.05)。97.7%的波兰人和90.0%的波斯尼亚CD患者携带至少一个突变的ABCB1等位基因。在这两个人群中未发现ABCB1 SNP与CD之间存在关联。总之,两个ABCB1 SNP可能对波兰和B&H人群的CD易感性没有影响。有必要对两个人群中的较大样本进行进一步研究。这两个ABCB1 SNP可能对波兰和B&H人群的CD易感性没有影响。有必要对两个人群中的较大样本进行进一步研究。这两个ABCB1 SNP可能对波兰和B&H人群的CD易感性没有影响。有必要对两个人群中的较大样本进行进一步研究。
