Increased Burden Of Rare Genetic Variations Found In Schizophrenia

People with schizophrenia bear an "increased burden" of rare deletions and duplications of genetic material, genome-wide, say researchers. Although many of us have these changes in our genetic material, they are about 15 percent more frequent in people with schizophrenia. The researchers also discovered two large areas of chromosomal deletions that confer a great deal of risk for the disorder and confirmed involvement of a third previously reported area.
