Study reveals value of schizophrenia-related gene variation
...ul gene variant, the fact that it sometimes is not reveals that it can react with environmental or other genetic factors to result in illness. "If we can find a way to intervene in those interactions, then we may be able to avert disease and harness how this gene variation may help us," Philibert added. ...Individuals with genetic conditions twice as likely to report health insurance denial
