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%...

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...

Area of Science:

Transcriptomics
Bioinformatics
Computational Biology

Background:

Differential expression analysis in transcriptomics is challenging due to transcript abundance uncertainties.
Ignoring these uncertainties can inflate false positives or reduce statistical power.

Conclusions:

mehenDi provides a powerful approach for differential transcript expression analysis by incorporating uncertainty.
The method can detect differential expression signals at both transcript and group levels (inner nodes).
mehenDi enhances the interpretability and accuracy of transcriptomics data analysis.
