Validating Candidate Congenital Heart Disease Genes in Drosophila

[Abstract]  Genomic sequencing efforts can implicate large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system to validate candidate gene association with pathology is therefore useful. We present such a system employing Drosophila to validate candidate congenital heart disease (CHD) genes. The protocols exploit comprehensive libraries of UAS-GeneX-RNAi fly strains that when crossed into a 4XHand-Gal4 genetic background afford highly efficient cardiac-specific knockdown of endogenous fly orthologs of human genes. A panel of quantitative assays evaluates phenotypic severity across multiple cardiac parameters. These include developmental lethality, larva and adult heart morphology, and adult longevity. These ... [摘要]  基因组测序工作可能涉及大量基因和从头突变作为潜在的疾病风险因素。 因此,用于验证候选基因与病理学关联的高通量体内模型系统是有用的。 我们提出了使用果蝇来验证候选先天性心脏病(CHD)基因的这种系统。 这些方案利用了UAS-GeneX-RNAi飞行菌株的综合文库,当跨越4XHand-Gal4遗传背景时,提供了人类基因内源性直向同源物的高效心脏特异性敲低。 一组定量测定评估多种心脏参数的表型严重程度。 这些包括发育致死率,幼虫和成人心脏形态以及成年人的长寿。 这些方案最近被用于评估患者全外显子测序所涉及的100多个候选CHD基因(Zhu等,2017)。
