Fig. 2

Non-synonymous variants in oxidative phosphorylation genes among patients with and without elevated blood lactate levels. Patients with high blood lactate (n = 36) are on the left of the solid black line; patients with normal lactate levels (n = 37) are on the right. Each patient is represented by a column and each variant location by a row. Non-synonymous variants are shown as red squares. To simplify the figure, nucleotide positions (rows) without variants are not shown
