Although there is currently no evidence of an association between polymorphisms in OXTR and AVPR, and schizophrenia, there are reports of associations between OXTR and AVPR polymorphisms and traits associated with the disease, such as attention (the main cognitive domain that is impaired in this disorder; Powell et al., 2009; Ratajczak et al., 2013) and negative symptomatology. The gene discussed is OXTR; the disease is schizophrenia.
