Comparison of Mitochondrial Mutation Spectra in Ageing Human Colonic Epithelium and Disease: Absence of Evidence for Purifying Selection in Somatic Mitochondrial DNA Point Mutations
Figure 1
Gene location and types of mutations observed in ageing, population, and disease.
A: Gene location of mutations. Data are represented as the percentage of the total coding region mutations. Contingency analysis with Bonferroni correction for multiple testing was carried out on the frequencies of the changes in each gene type (ageing n = 117, population n = 182, disease n = 176). Thresholds for statistical significance are; ***<0.0003, ** 0.003, * = 0.017. B: Types of changes observed in ageing, population and disease. Data are represented as the percentage of the total coding region mutations. Contingency analysis with Bonferroni correction for multiple testing was carried out on the frequencies of the changes in each mutational category. Thresholds for statistical significance are; ***<0.0003, ** 0.003, * = 0.017.
