KIAA0319 has been shown to be a target of T‐Brain‐1 (TBR1), a transcription factor implicated in autism which regulates different brain developmental processes, such as neuronal migration, axon guidance (Chuang, Huang, & Hsueh, 2015) and the determination of left–right asymmetries in bilaterians (Kitaguchi, Mizugishi, Hatayama, Aruga, & Mikoshiba, 2002). Here, TBR1 is linked to autism.
