Figure 2From: Mutational spectrum of the APC and MUTYH genes and genotype–phenotype correlations in Brazilian FAP, AFAP, and MAP patientsAge of onset per group. The graph shows the distribution and the mean (horizontal line) age of onset for each of the five defined groups. Groups 1, 2, and 4 patients had a significantly later age of onset than group 3 patients (t = 2.35 p = 0.024; t = 2.15 p = 0.04; t = 2.01 p = 0.05, respectively).Back to article page
