CMT64 cell line
Genomic DNA was isolated from cell lines and C57Bl/6 mice using the DNeasy Blood and Tissue Kit (Qiagen) per manufacturers protocol.  Whole exome sequencing was completed by the sequencing facility at Frederick National Laboratory for Cancer Reseach (Leidos Biomdical Research, Inc.).  Exome samples were pooled and sequenced on NovaSeq 6000 S1 run using Agilent SureSelect XT Mouse All Exon and paired-end sequencing mode.
