Dataset contains Next-Generation Sequencing (NGS) data tracking somatic mutations in rats over multiple time points.

Each row represents a specific nucleotide variant, detailing the reference (REF) and alternative (ALT) nucleotides, along with functional annotations such as functional class, codon change, and amino acid change (if applicable). Mutation frequencies are provided for individual rats across various time points. The sample identifiers follow the format rXX-Y, where rXX represents the rat ID and Y indicates the week of sample collection. (XLSX)
