VUS is p.R1546Q variant of unknown significance, AVG beta is mean beta value for each of three groups, delta beta is differences between mean of KDM5C mutations cases (N = 10) and controls (N = 19). Delta Z is delta beta divided by standard deviation of combined cases and controls data. All 13 CpG sites were located within CpG islands.
