ACTN4 and glomerular disorder: In Fig 1, boxplots represent the distribution of the log-transformed mRNA (2-ΔΔCt) of alpha-actinin-4, podocin, podocalyxin, TGF-β1, CTGF, and VEGF-A for each glomerulopathy in relation to the mRNA expression in control biopsies, based on the minimum, 25th percentile, median, 75th percentile, and maximum values; the upper and lower whisker indicate the highest and lowest value (Kruskal-Wallis test).
