Finally, because OC behaviors are associated with BE (Kessler et al. 2016; Moore et al. 2017; Wilfley et al. 2016) and hyperphagia in PWS (Griggs et al. 2015), we employed a battery of tests to assess anxiety-like and compulsive-like behaviors and post-BE training behaviors in Cyfip1 haploinsufficient mice, including compulsive-like eating and concomitant behaviors in the light/dark conflict test (Babbs et al. 2018; Kirkpatrick et al. 2017). The gene discussed is CYFIP1; the disease is Anxiety.
