Altered expression of mRNA for proteins involved in in microtubule-associated tracking complex of NR2B such as KIF17, APBA1, CASK, mLin7A, and mLin7C in cortical layers III and IV of schizophrenia patients, which overlapped with NR2B but not NR2A transcripts suggests that NR2B-containing NMDA receptor transport could be selectively compromised in schizophrenia (Kristiansen et al., 2010a,b). The gene discussed is GRIN2B; the disease is schizophrenia.
