KLF13 and neurodevelopmental disorder: The last class is associated with nerve regulation; e.g., neurexin-1a is strongly associated with neurodevelopmental disorders, so knockout mice exhibited social deficits and increased levels of aggression (Armstrong et al., 2020); Krueppel-like factor 13 inhibits neurite/axon growth in hippocampal neurons partially by inhibiting the cAMP signaling pathway (Ávila-Mendoza et al., 2020).
