Leveraging independent single-cell and single-nucleus RNA sequencing datasets derived from human brain-relevant cell and tissue types, we identify a significant increase in gene expression variability driven by the autosomal aneuploidy trisomy 21 (T21) as well as autism-associated chromodomain helicase DNA binding protein 8 (CHD8) haploinsufficiency. Our analyses are consistent with a global and, in part, stochastic increase in variability, which is uncoupled from changes in transcript abundance. Highly variable genes tend to be cell-type specific with modest enrichment for repressive H3K27me3, while least variable genes are more likely to be constrained and associated with active histone marks.

The receptor tyrosine kinase gene RET is the most significant contributor, implicated in 12%-50% of individuals depending on the phenotype. RET plays a critical role in ENS precursor proliferation and migration, and defects in these processes lead to HSCR. However, the functional impact of RET pathogenic variants and their mechanisms of disease remain poorly understood. To address this, we investigated proliferative and migratory phenotypes in a RET-dependent neural crest-derived cell line harboring one of five missense (c.166C>A [p.Leu56Met]; c.532G>C [p.Glu178Gln]; c.2372A>T [p.Tyr791Phe]; c.2765C>A [p.Ser922Tyr]; or c.2994T>A [p.Phe998Leu]) or three nonsense (c.612C>A, c.2308C>T, or c.2943C>G) heterozygous pathogenic RET variants. Using cDNA- and CRISPR-based prime reverse insertion mechanism engineering (PRIME) editing coupled with quantitative proliferation and migration assays, we observed significant losses in proliferation and migration in three missense (c.612C>A [p.Tyr204<sup>∗</sup>]; c.2308C>T [p.Arg770<sup>∗</sup>]; and c.2943C>G [p.Tyr981<sup>∗</sup>]) and all nonsense variants. Notably, the c.2372A>T (p.Tyr791Phe) missense variant, whose pathogenicity has been debated, appears benign. Importantly, the severity of migration loss did not consistently correlate with proliferation defects, and the phenotypic severity of nonsense variants was independent of their position within the RET protein.

Understanding the role of immunogenetic variation in risk for CMV infection can provide insight into the immune control of this ubiquitous pathogen. Here, we evaluated the association of human leukocyte antigen (HLA) genetic variation with CMV seropositivity in more than 518,000 individuals from two independent cohorts.

Along with the opportunities that local ancestry provides, there exist challenges preventing its full usage in genetic analyses. In this review, we first summarize methods for local ancestry inference and illustrate how local ancestry can be utilized in various analyses, including admixture mapping, association testing, and polygenic risk score construction. In addition, we discuss current challenges in research involving local ancestry, both in terms of the inference itself and its role in genetic association studies. We further pinpoint some future study directions and methodology development opportunities to help more effectively incorporate local ancestry in genetic analyses.
