  • 摘要:   目的  探讨单效应汇总(sum of single effects, SuSiE)回归模型在多组学数据共定位分析中的应用。  方法  以多组学模拟数据为例,介绍单效应汇总回归模型的基本原理和R软件分析。  结果  SuSiE回归模型通过利用单核苷酸多态性(single nucleotide polymorphism,SNPs)位点之间因连锁不平衡(linkage disequilibrium,LD)产生的相关性,允许在有多个因果变异的情况下,正确识别两个组学数据与表型相关的共定位点。  结论  相对于传统方法,SuSiE回归模型拓展了单一因果变异假设这一适用条件,且计算效率较高,从而有助于利用多组学数据检测多个潜在与疾病相关联位点。

    A为三元图,蓝色区域对应于共定位的高概率(PP4>50%),橙色区域对应于两种表型为不同因果变异的高概率(PP3>50%),灰色区域对应于未能确定或拒绝共定位的概率。B、C、D、E分别为H0~H4示意图。

    Figure  1.  The schematic diagram of the posteriori probabilities of colocalization analyse and the five hypotheses

    A is a triplet plot, where the blue area corresponds to a high probability of colocalization (PP4 > 50%), the orange area corresponds to a high probability of the two phenotypes having different causal variations (PP3 > 50%), and the gray area corresponds to a probability of failing to determine or rejecting colocalization. B, C, D and E are H0-H4 respectively.

    左侧是基因组和转录组的局部曼哈顿图。右侧为不同p12值时H0~H4假设的先验概率和后验概率,绿色框表示PP4 > 0.9,虚线表示当前的p12值,该值位于绿色框内,表明p12设为当前值时PP4 > 0.9的结论稳定。

    On the left is a local Manhattan map of the genome and transcriptome. The right side is the prior probability and posterior probability of H0-H4 hypothesis with different p12 values, and the green box represents PP4 > 0.9, the dotted line indicates the current p12 value. The value is in the green box, indicating that when the p12 is set to the current value PP4 > The conclusion of 0.9 is stable.
