Fig. 2: Two-dimensional ddPCR scatter plots for the analysis of the TCF20 variant.

A Proband’s ddPCR scatter plot from peripheral blood. B Proband’s father’s ddPCR scatter plot from urothelial cells. Colored dots represent single droplets of emulsion carrying amplified DNA harboring the variant (green) or wildtype DNA (blue). Black dots represent droplets with no amplification of the target DNA
