CNTNAP5 and autism spectrum disorder: Common variants implicating CNTNAP5 have previously been associated with the posterior cortical atrophy variant of AD (Schott et al., 2016), BIP (Djurovic et al., 2010), and response to antipsychotic treatment in schizophrenia (Yu et al., 2018), while rare variants within CNTNAP5 have previously been associated with autism spectrum disorders (Pagnamenta et al., 2010).
