NMDA receptors are comprised of two obligatory (NR1) and two regulatory (NR2) subunits (Cull-Candy and Leszkiewicz, 2004), have many critical roles in neural plasticity (Ishii et al., 1993), and their malfunctions have been implicated in many neurological disorders (Tarabeux et al., 2011; Lakhan et al., 2013; Lee et al., 2015). The gene discussed is GRIN1; the disease is nervous system disorder.
