Circulating levels of soluble intercellular adhesion molecule-1, soluble P-selectin, and soluble E-selectin have been associated with variation at the ABO locus. To evaluate these associations and the effect sizes, we performed a meta-analysis with new and previous reported data for polymorphism rs579459.
Compared with major allele homozygotes, heterozygotes and minor allele homozygotes had 4.6% (95% CI, 3.4%-5.8%, P=7.3 × 10(-14)) and 7.2% (95% CI, 4.7%-9.7%, P=1.5 × 10(-8)), respectively, lower soluble intercellular adhesion molecule-1 levels (n=33 671). An allele dose-dependent association also was observed for soluble P-selectin (n=4921) with heterozygotes and minor allele homozygotes having 11.5% (95% CI, 7.2%-15.8%, P=1.7 × 10(-7)) and 18.6% (95% CI, 9.1%-28.1%, P=1.2 × 10(-4)), respectively, lower levels than in major allele homozygotes. A larger effect size, again consistent with an additive genetic model, was seen for soluble E-selectin (n=2860) whose level was 25.6% (95% CI, 19.0%-32.2%, P=2.1 × 10(-14)) lower in heterozygotes and 43.3% (95% CI, 36.9%-49.3%, P=4.3 × 10(-42)) lower in minor allele homozygotes than in major allele homozygotes.
The data support the association of variation at the ABO locus with soluble intercellular adhesion molecule-1, soluble P-selectin, and soluble E-selectin levels.
可溶性细胞间黏附分子-1、可溶性P-选择素和可溶性E-选择素的循环水平与ABO基因座的变异有关。为了评估这些关联及效应大小,我们对多态性rs579459的新数据和先前报道的数据进行了荟萃分析。
与主要等位基因纯合子相比,杂合子和次要等位基因纯合子的可溶性细胞间黏附分子-1水平分别降低了4.6%(95%CI,3.4%-5.8%,P=7.3×10⁻¹⁴)和7.2%(95%CI,4.7%-9.7%,P=1.5×10⁻⁸)(n=33671)。对于可溶性P-选择素(n=4921)也观察到了等位基因剂量依赖性关联,杂合子和次要等位基因纯合子的水平分别比主要等位基因纯合子低11.5%(95%CI,7.2%-15.8%,P=1.7×10⁻⁷)和18.6%(95%CI,9.1%-28.1%,P=1.2×10⁻⁴)。对于可溶性E-选择素(n=2860),观察到更大的效应大小,同样符合加性遗传模型,杂合子的水平比主要等位基因纯合子低25.6%(95%CI,19.0%-32.2%,P=2.1×10⁻¹⁴),次要等位基因纯合子的水平比主要等位基因纯合子低43.3%(95%CI,36.9%-49.3%,P=4.3×10⁻⁴²)。
数据支持ABO基因座变异与可溶性细胞间黏附分子-1、可溶性P-选择素和可溶性E-选择素水平之间的关联。
