Correlation between CpG methylation rate in distal D4Z4 or repeat length, and patient phenotypes. A, C Scatter plots of mean CpG methylation rate in distal D4Z4 repeat units and age at disease onset (A) or age at hospital inspection (C) in FSHD1. B, D Scatter plots of D4Z4 repeat number and age at disease onset (B) or age at hospital inspection (D) in FSHD1. Correlation coefficients were calculated by linear regression. Two samples were removed due to unknown exact ages at onset of the disease
