abstract = {Genetic variants (both coding and noncoding) can impact
gene function and expression, driving disease mechanisms
such as cancer progression. The systematic study of
endogenous genetic variants is hindered by inefficient
precision editing tools, combined with technical limitations
in confidently linking genotypes to gene expression at
single-cell resolution. We developed single-cell DNA-RNA
sequencing (SDR-seq) to simultaneously profile up to 480
genomic DNA loci and genes in thousands of single cells,
enabling accurate determination of coding and noncoding
variant zygosity alongside associated gene expression
changes. Using SDR-seq, we associate coding and noncoding
variants with distinct gene expression in human induced
pluripotent stem cells. Furthermore, we demonstrate that in
primary B cell lymphoma samples, cells with a higher
mutational burden exhibit elevated B cell receptor signaling
and tumorigenic gene expression. SDR-seq provides a powerful
platform to dissect regulatory mechanisms encoded by genetic
variants, advancing our understanding of gene expression
regulation and its implications for disease.},
