Dataset contains Next-Generation Sequencing (NGS) data tracking somatic mutations in mice 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 mice across various time points. The sample identifiers follow the format XXXX-Y, XXXX-YY or XXX-Y, where XXXX or XXX represents the mouse ID and YY or Y indicates the day of sample collection. (XLSX)
