In patients with schizophrenia, LIM Kinase (LIMK) was also found to be deregulated (Datta et al., 2015; Zhao et al., 2015), and a direct molecular link was established between LIMK and neuregulin 1, which is encoded by a schizophrenia-susceptibility gene (Yin et al., 2013). Here, LIMK1 is linked to schizophrenia.
