Despite extensive exploration of the monogenic causes of CHD over the last decades, ∼55% of cases still lack a molecular diagnosis. Investigating digenic interactions, the simplest form of oligogenic interactions, using high-throughput sequencing data can elucidate additional genetic factors contributing to the disease. Here, we conducted a comprehensive analysis of digenic interactions in CHD by utilizing a large CHD trio exome sequencing cohort, comprising 3,910 CHD and 3,644 control trios. We extracted pairs of presumably deleterious rare variants observed in CHD-affected and unaffected children but not in a single parent. Burden testing of gene pairs derived from these variant pairs revealed 29 nominally significant gene pairs. These gene pairs showed a significant enrichment for known CHD genes (p < 1.0 × 10<sup>-4</sup>) and exhibited a shorter average biological distance to known CHD genes than expected by chance (p = 3.0 × 10<sup>-4</sup>). Utilizing three complementary biological relatedness approaches including network analyses, biological distance calculations, and candidate gene prioritization methods, we prioritized 10 final gene pairs that are likely to underlie CHD. Analysis of bulk RNA-sequencing data showed that these genes are highly expressed in the developing embryonic heart (p < 1 × 10<sup>-4</sup>). In conclusion, our findings suggest the potential role of digenic interactions in CHD pathogenesis and provide insights into unresolved molecular diagnoses.

Both probands carry PIGA c.395C>G (p.Ser132Cys), an ultra-rare variant predicted to be damaging. Strikingly, the maternal grandfather and a great uncle also carry the same PIGA variant, but neither presents with symptoms associated with PIGA-CDG. We hypothesized that genetic modifiers might contribute to this reduced penetrance. Using whole-genome sequencing and pedigree analysis, we identified possible susceptibility variants found in the probands and not in the carriers and possible protective variants found in the carriers and not in the probands. Candidate genetic modifier variants included heterozygous, damaging variants in three genes involved directly in glycosylphosphatidylinositol (GPI)-anchor biosynthesis and additional variants in other glycosylation pathways or encoding GPI-anchored proteins. Using a Drosophila eye-based model, we tested modifiers identified through genome sequencing. Loss of CNTN2, a predicted protective modifier that encodes a GPI-anchored protein responsible for neuron/glial interactions, rescues loss of PIGA in the eye-based model, as we predict in the family. Further testing found that the loss of CNTN2 also rescues PIGA-CDG-specific phenotypes, including seizures and climbing defects in Drosophila neurological models of PIGA-CDG.

Simulating linkage-disequilibrium-informed admixed haplotypes under a variety of 2- and 3-way admixture models, we implemented a standard LAI pipeline, testing the impact of reference panel composition, DNA data type, demography, and software parameters to quantify ancestry-specific LAI accuracy. We observe that across all models, AMR tracts have notably reduced LAI accuracy as compared to EUR and AFR tracts, with true positive rate means for AMR ranging from 88% to 94%, EUR from 96% to 99%, and AFR from 98% to 99%. When LAI miscalls occurred, they most frequently erroneously called EUR ancestry in true AMR sites. Concerning reference panel curation, we find that using a reference panel well matched to the target population, even with a smaller sample size, was accurate and the most computationally efficient. Imputation did not harm LAI performance in our tests; rather, we observed that higher variant density improved accuracy.
