Hybrid untargeted short-read and targeted long-read RNA sequencing facilitates genotype-phenotype associations at single-cell resolution.

Combination of SR-WTA (broad transcriptome coverage) + LR-Twist (50-gene targeted long-read panel) in a Snakemake pipeline for simultaneous variant and expression detection at single-cell resolution

The authors evaluate three single-cell RNA sequencing strategies (SR-WTA, LR-WTA, targeted LR-Twist) and develop a hybrid SR-WTA + LR-Twist strategy. The combination provides broad transcriptome coverage (short-read) while enriching a 50-gene panel for deep variant detection by long-read. The open-source Snakemake pipeline is applicable to genotype-phenotype association studies at single-cell resolution, with application to rare disease diagnostics.

The hybrid short-read/long-read strategy for single-cell RNA-seq fills an important blind spot: pure long-read lacks coverage, pure short-read cannot resolve complex splicing variants. This 50-gene targeted approach is directly transposable to rare disease diagnostics where single-cell transcriptomics is beginning to find its place for intronic and splicing variants unsolved by WES/WGS.
