Copy number variants (CNVs) are emerging as a promising hypothesis to explain the hereditary basis of schizophrenia. CNVs refer to variations in the number of copies of a particular gene or genes. Some CNVs have been found to be associated with an increased risk of developing schizophrenia. This hypothesis suggests that multiple CNVs may interact with each other and with environmental factors to increase the risk of developing schizophrenia. A recent study found that rare CNVs are associated with a significant risk of developing schizophrenia and can account for up to 2-3% of cases.
