We further measured the mRNA levels of a number of genes known to be involved in the pathology of psychiatric disorders, including Bdnf (Schmidt et al., 2011), Fosb (Heller et al., 2014), Drd1/2 (Le-Niculescu et al., 2011; Zhang et al., 2014), Grik2 (Shibata et al., 2002), Hdac1/9v (Macpherson et al., 2015; Wu et al., 2015; Subburaju et al., 2016), and Grin2a/b (Lemke et al., 2014; Liu et al., 2015). The gene discussed is HDAC1; the disease is psychiatric disorder.
