Schematic overview of the gene mutations per cell line, obtained with targeted Haloplex sequencing. A red box represents a missense mutation, green a nonsense mutation, yellow a frameshift deletion, blue a frameshift insertion, purple a splice site mutation, grey an exomic deletion, orange both a missense mutation and a frameshift deletion, blue both a missense mutations and a splice site mutation. For CDKN2A encoding the p16 protein, the number between brackets indicates a single (1) or homozygous (2) loss of the locus. The mutation annotations per cell line and gene can be found in table S3.
