WDR45 and Tremor: A modified SHIRPA analysis revealed that both male and female mutants were more prone to show tremors with significant differences at 20 months of age (number of animals with tremor: 10/10 Wdr45−/−, 8/10 Wdr45−/+, and 10/10 Wdr45−/Y vs 4/10 Wdr45+/+ and 6/10 Wdr45+/Y; Fisher’s Exact test).
