Table 4. Estimates of the PCR error rate for the different mutation types.

Mutation type	PCR error rate (per site per cycle)	Mutation frequency / PCR error rate
A>C/T>G	6.9 x 10−8	6.4
C>G/G>C	3.0 x 10−7	3.7
A>T/T>A	7.5 x 10−7	1.9
A>G/T>C	1.5 x 10−6	2.2
C>T/G>A (non-CpG)	1.0 x 10−6	17.0
G>T/C>A	1.3 x 10−6	16.9
C>T/G>A (CpG)	2.6 x 10−6	28.5
