NTN1 and psychiatric disorder: In humans, mounting evidence from postmortem (Manitt et al., 2013; Torres-Berrío et al., 2017) and genetic studies (Grant et al., 2012; Vosberg et al., 2018; Cross-Disorder Group of the Psychiatric Genomics Consortium, 2019; Strawbridge et al., 2019) shows that altered expression and polymorphisms in the DCC and Netrin-1 genes associate with psychiatric disorders (for review, see Torres-Berrío et al., 2020; Vosberg et al., 2020).
