This region corresponds to the teneurin C-terminal associated peptide (TCAP), which is thought to function independently of intact teneurins to stimulate neurite outgrowth, regulate dendritic morphology and modulate anxiety behaviors in rats (Qian et al., 2004; Wang et al., 2005; Al Chawaf et al., 2007; Tan et al., 2008). The gene discussed is TCAP; the disease is Anxiety.
