本研究提出连锁不平衡SNP对效应相关回归(LDSPEC)新方法,用于估计邻近SNP衍生等位基因因果疾病效应量之间的相关性,模拟显示其估计稳健。分析英国生物银行70种疾病和性状(平均N=305,646),检测到显著非零的SNP对效应相关性(如低频正连锁不平衡0-100 bp SNP对为-0.37±0.09),该相关性随距离衰减,并随等位基因频率及SNP间连锁不平衡变化。具有共享功能的SNP对效应相关性更强且跨越更远基因组距离。因此,SNP遗传力估计值小于SNP因果效应量方差总和,在某些功能注释中尤为明显。正向模拟涉及稳定选择,重现了上述发现,提示连锁掩蔽作用:包含对疾病效应相反的连锁SNP的单倍型对适合度影响降低,从而逃避负选择。
为什么值得关注
编辑短评
邻近 SNP 的因果效应并不独立,同一调控单元内倾向负相关;该模式由稳定选择下的连锁掩蔽产生,打破了遗传力分析里 SNP 效应独立的经典假设,会让高功能区域遗传力被高估。
