Table 2. Mutation frequency as a function of mutation type.

Mutation type	Mutation frequency
A>C/T>G	4.4 x 10−7
C>G/G>C	1.1 x 10−6
A>T/T>A	1.4 x 10−6
A>G/T>C	3.3 x 10−6
C>T/G>A (non-CpG)	1.7 x 10−5
G>T /C>A	2.2 x 10−5
C>T/G>A (CpG)	7.4 x 10−5

Data for the PTPN11, MECP2, and FGFR3 experiments combined. Unlike Fig 3, the mutation frequencies are not the sums of all three possible mutations at each base pair.
