TG lines for GABAergic neurons [e.g. tg (dlx6a-1.4kbdlx5a/dlx6a:GFP) (Hoffman et al., 2016)] also offer an important neuron type for examining eEDCs effects as a deficit in GABAergic neurons in the forebrain, particularly in the telencephalon, has been proposed to be associated wih night-time hyperactive behaviour phenotype in an autism model Contactin Associated Protein-like 2 (CNTNAP2) mutant zebrafish (Hoffman et al., 2016). The gene discussed is CNTNAP2; the disease is autism.
