基于多组学整合的疾病特异性的数量性状位点识别方法

By using a multi-omics integration approach, whole-genome sequencing and molecular phenotypic data were obtained, and effect estimates of association pairs were screened and calculated to identify Parkinson's disease-specific pathogenic genetic variants. This solved the problem of the inability to accurately identify pathogenic genetic variants of Parkinson's disease in existing technologies and enabled the accurate identification of the regulatory effects of genetic variants.

AI Technical Summary

Technical Problem

Current technologies cannot accurately identify disease-specific pathogenic genetic variations in Parkinson's disease, and it is difficult to reveal the differences in the regulatory effects of genetic variations between Parkinson's patients and healthy individuals.

Method used

By using a multi-omics integration approach, whole-genome sequencing data and molecular phenotypic data were obtained, the significance probability values ​​of association pairs were determined, consistent association pairs between healthy and diseased subjects were screened, effect estimates were calculated, and quantitative trait loci associated with Parkinson's disease were identified.

Benefits of technology

Accurately identify pathogenic genetic variants related to Parkinson's disease, eliminate false positive interference, ensure the reliability of the genetic basis, and reveal the differences in the regulatory effects of genetic variants between Parkinson's patients and healthy individuals.

Abstract

本申请涉及一种基于多组学整合的疾病特异性的数量性状位点识别方法。所述方法包括:获取目标对象的全基因组测序数据的变异位点、分子表型数据的分子表型及分子丰度;基于变异位点与分子丰度,确定由变异位点与分子表型构成的关联对的关联显著性概率值,基于关联显著性概率值和条件分析从关联对中筛选第一关联对;确定正常关联对和患病关联对中一致的第二关联对,确定第二关联对中具有疾病交互效应的第三关联对;计算各第三关联对的第一效应估计值和第二效应估计值;基于第三关联对的第一效应估计值和第二效应估计值,确定与帕金森病相关的目标关联对,并以目标关联对为识别出的数量性状位点。采用本方法能够准确识别帕金森特异的致病性遗传变异。
