Data from: IARC TP53 Mutation Database (http://www-p53.iarc.fr/) (ref 38). Non-XP Basal cell carcinoma data from: Basal cell carcinoma NOS (C44._) data set restricted to the skin with XP germline mutations filtered out. Non-XP Squamous cell carcinoma data from: Squamous cell carcinoma NOS data set restricted to the skin and with XP germline mutations excluded.
Both the transcribed and non-transcribed strands contain a mCG sequence. If the strand contains a PymCG sequence capable of dimer-mediated C→T mutations, the sequence is given. If the strand does not contain a PymCG sequence, the abbreviation na for not applicable is given.
