The Finnish Adoptive Family Study of Schizophrenia: differences in somatic diseases and conditions between adoptees with high or low genetic risk for schizophrenia spectrum disorders.

More research is required for specific somatic diseases in study populations that can differentiate between the effects of genetic and environmental factors.
