RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Area of Science:

Genomics
Bioinformatics
Molecular Biology

Background:

Single nucleotide variant identification is standard in droplet-based single-cell RNA sequencing (scRNA-seq).
Existing pipelines lack optimization for variant calling accuracy and do not leverage molecular duplicates for co-expression analysis.

Purpose of the Study:

Introduce scSNV, a novel pipeline to enhance variant calling accuracy in scRNA-seq.
Utilize molecular duplicates to detect variant co-expression effectively.

Main Methods:

Developed scSNV pipeline to collapse molecular duplicates.
Implemented algorithms for accurate variant identification and co-expression analysis.

Main Results:

scSNV demonstrates high speed and a reduced false-positive variant call rate.
The pipeline successfully co-detects genetic variants and A>G RNA edits across twenty-two samples.

Conclusions:

scSNV provides an optimized solution for variant calling and co-expression analysis in scRNA-seq.
The method improves the utility of molecular duplicates for comprehensive genetic and RNA editing insights.
