Single-Cell Sequencing

Definition
AI-generated

Single-cell sequencing profiles DNA or RNA from individual cells rather than bulk tissue, revealing cell-type-specific genotypes, expression, and heterogeneity in large cell populations.

Why it matters in GWAS

Single-cell data can refine which cell types and states carry GWAS effects (e.g. expression and chromatin programs) and support mechanistic interpretation beyond bulk-level associations.

Example usage

"Quality-controlled Single-Cell Sequencing data were used to prioritize robust loci and downstream functional follow-up."
