Schizophrenia is a spectrum of disorders defined by abnormalities in one or more areas including delusions, hallucinations, disorganized thinking or speech, grossly disorganized or abnormal motor behaviors including catatonia and other negative symptoms (American Psychology Association, 2013). Schizophrenia is inherited on autosomal chromosome 8p12. Neuregulin 1 (NRG1), an epithelial growth factor protein, located at 8p12, has been identified as being a nucleotide variation of the single-nucleotide polymorphism (SNP), rs833497 located on chromosome 18q21.1 that is associated with schizophrenia.
