(A) The TP53 mutation distribution for 16 cancer types with
sufficient available data and frequency of TP53 alteration.
Each histogram depicts the number of mutations found at each position along the
p53 protein coding sequence, with the transactivation domain (TAD), DNA-binding
domain (DBD), and oligomerization domain (OD) illustrated below. Symbol color
indicates mutation type, including missense (green), nonsense (red), inframe
indels (black), or multiple mutation types (purple). Data source: MSKCC cbio
portal (Gao, Schultz, Sci Signal, 2013). (B) Multiple avenues to inactivating
the second allele of TP53.
