The gRNAs were ranked based on how many times they were found in the top 98% percentile of abundance (considered on a per-mouse basis). Hits were defined as those found in the 98th percentile of >30% of the mice (n = 40 mice in total). The number of mice in which the gRNAs were found in the 98th percentile and the z-score for the specific gRNA is shown. Details of the specific gRNAs and the mice in which they were identified are provided in Supplementary Tables S1 and S2.
