TransAT

TransAT (Transcript Annotation Tool) is an R package that facilitates the annotation of genetic variants associated with RNA transcripts. It allows users to input transcript IDs and obtain corresponding single nucleotide polymorphism (SNP) information, including SNP IDs, genomic positions, and allele frequencies from various global populations.

The tool addresses the need for a comprehensive annotation resource that can directly link transcript IDs to their respective genetic variants. While existing tools like SNPnexus and VariED provide variant annotations, they cannot input transcript IDs and retrieve the associated variants' genomic positions.

TransAT offers a streamlined workflow, enabling users to obtain relevant genetic information in just two simple command lines. By leveraging publicly available data, the tool extracts and presents the requested information in a user-friendly, downloadable format.

The significance of TransAT lies in its potential to aid physicians in making personalized treatment decisions. By providing easily accessible genetic annotations for specific transcripts, the tool can help identify pathogenic variants in individual patients. Additionally, including allele frequencies from various global ethnic populations underscores the importance of considering ethnicity when assessing patient pathogenicity.
