Abstract Congenital cardiovascular disease (CHD) includes a complicated genetic etiology, and recent research claim that 414864-00-9 high penetrance mutations might take into account only a part of disease. Inside a multi-institutional cohort surveyed by exome sequencing, merging evaluation of 987 414864-00-9 people (finding cohort of 59 affected trios and 59 control trios, and a replication cohort of 100 affected singletons and 533 unaffected singletons) we observe variant at book and 414864-00-9 known loci related to a specific cardiac malformation the atrioventricular septal defect (AVSD). In a primary analysis, by combining developmental coexpression networks with inheritance modeling, we identify a mutation in the DNA binding domain of (p.R175W). We show that p.R175W changes the transcriptional activity of Nr1d2 using an transactivation model in HUVEC cells. Finally, we demonstrate previously unrecognized cardiovascular malformations in the knockout mouse. In secondary analyses IL-10C we map genetic variation to protein-interaction networks suggesting a role for two collagen genes in AVSD, which we corroborate by burden testing in a second replication cohort of 100 AVSDs and 533 controls (= 8.37e-08). Finally, we apply a rare-disease inheritance model to identify variation in genes previously associated with CHD (and in 14 of 59 trios, greatly exceeding variation in control trios without CHD (= 9.60e-06). In total, 32% of trios carried at least one putatively disease-associated variant across 19 loci,suggesting that inherited and variation across a 414864-00-9 heterogeneous group of loci may contribute to disease risk. Author Summary Congenital heart disease (CHD) is a leading cause of childhood morbidity in the developed world. There are few prevalent clinical risk factors and though it is possible that up to 90% of risk for CHD may be genetic, the number of genes clinically associated with disease is small. Rather than grouping disparate CHD phenotypes as other studies have done, we studied a single specific malformation- the atrioventricular septal defect (AVSD). Instead of recurrent variation in a handful of genes, we observed and inherited variation in 19 genes associated with human disease, syndromic loci, and genes implicated in cardiac development by mouse knockout. The number of loci identified 414864-00-9 support the longstanding hypothesis of a complex oligogenic inheritance for a single malformation and suggest that analyses of CHD data to include inherited variation may uncover additional loci contributing risk for cardiac malformations. Introduction Congenital heart disease (CHD) is the most common congenital malformation and the most common cause of mortality during the first year of life in the United States [1,2]. Most cases occur sporadically without a strong family history or identifiable genetic syndrome, and the primary heritable basis of most.
