Genetic Studies Have Found That Schizophrenia Was Associated with Literally

Genetic studies have found that schizophrenia was associated with literally thousands of gene variations, both common and rare. Which of the following is NOT one of the three important results that emerged from this research?

A) Genes associated with a particular chromosome location have been linked directly to the development of both schizophrenia and bipolar disorder.
B) A large number of gene variants were found to occur on a specific chromosome that is also known to harbor genes that are involved in the immune response.
C) Several chromosome locations implicated in the development of schizophrenia are associated with genes that influence brain development, memory, and cognition.
D) Some of the same unique genetic patterns associated with schizophrenia were also found to be associated with bipolar disorder, suggesting common genetic origins.
