Frequent mutations of the CA simple sequence repeat in intron 1 of EGFR in mismatch repair-deficient colorectal cancers

Figure 2 Graphical representation of the influence of the CA-SSRI genotype on EGFR mRNA expression in normal colon. Expression levels were determined by QRT-PCR. Relative expression levels are given in percent, relative to expression levels determined in normal colons with a 16/16 genotype. Median values with the corresponding standard deviations are indicated. Two by two comparisons, P > 0.468 (Mann-Whitney U test).
