Some of the genetic
factors that are being researched right now are multiple genes contributing to the disease (there are about a dozen genes that are leading candidates), and the possibility of
epigenetic interactions (that is, certain genes and other biological molecules that determine whether and when certain genes present in the body are turned
on or off) that may contribute to schizophrenia.

factors such as trauma
on the molecular level is environmental
