We developed MINTIE, a novel RNA-seq analysis pipeline, to detect all transcriptional variants, including difficult-to-find ones. MINTIE significantly outperforms existing methods in identifying novel disease variants.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Detecting all transcriptional variants from RNA-sequencing (RNA-seq) data is challenging with current methods.
  • Existing approaches are effective for known fusion genes but struggle with other complex transcriptomic variations.

Purpose of the Study:

  • To develop an integrated pipeline, MINTIE, for comprehensive identification of all transcriptomic variants from RNA-seq data.
  • To enable the discovery of novel disease-associated variants across diverse conditions.

Main Methods:

  • MINTIE utilizes a reference-free strategy, integrating de novo transcript assembly with differential expression analysis.
  • This approach specifically targets the identification of up-regulated novel variants in case samples.

Main Results:

  • MINTIE was compared against eight other RNA-seq analysis methods.
  • The pipeline successfully detected over 85% of variants, significantly outperforming all other tested approaches.

Conclusions:

  • MINTIE provides a robust and comprehensive solution for identifying a wide spectrum of transcriptomic variants.
  • This advancement is expected to facilitate the discovery of new disease-related variants in various pathologies.
