Fig. 6From: Longitudinal data in peripheral blood confirm that PM20D1 is a quantitative trait locus (QTL) for Alzheimer’s disease and implicate its dynamic role in disease progressionMethylation change as disease progresses modeled by β values regressed with Braak score at one of the representative CpG probes (cg26354017) from the ROSMAP brain samples. Scatter plot is colored by the allelic doses of rs708727 where red = 0 (GG), green = 1 (GA), and blue = 2 (AA). An overall linear fit line is also shown.
