FXS C1-cKO mice also spent more time interacting with a new mouse (stranger 2) rather than a familiar one (stranger 1) (Figure 2D), suggesting a more sociable phenotype and an improved social memory post Trpc1 deletion (social novelty index: FXS C1: mean = 0.47 ± 0.03, FXS C1-cKO: mean = 0.57 ± 0.01, p = 0.022). The gene discussed is TRPC1; the disease is fragile X syndrome.
