In relation to the CNVs most convincingly implicated in the risk for schizophrenia [9], [10], [22], we found a patient with a deletion of 328 kb erasing the 5′UTR and the first 3 exons of the NRXN1 gene (NM_004801.4) and two patients with a deletion in the 15q11.2 region. Here, NRXN1 is linked to schizophrenia.
