  1. Data provided is based on the experiments using Ube3atm1Alb mice in F1 hybrid 129S2-C57BL/6J background. The table provides the obtained effect size, number of mice needed per genotype for each behavioral test (with power equal to 0.95, 0.90, 0.80), and statistical test used. For rotarod calculations, we used the average performance over the 5 days, while for the nest building we used the data of the last test day
