Moreover, Arid1b+/− mice were not significantly different from Arid1b+/+ controls in the light/dark conflict task as both groups spent the similar amounts of time in the dark chamber (p < 0.05), had the same latency to the first transition (p < 0.05), and made similar transitions (p < 0.05), not demonstrating a clear anxiety-like phenotype. The gene discussed is ARID1B; the disease is Anxiety.
