A study in youth who are missing part of a chromosome is further implicating a suspect gene in schizophrenia. Youth with this genetic chromosomal deletion syndrome already had a nearly 30-fold higher-than-normal risk of schizophrenia, but those who also had one of two common versions of the suspect gene had worse symptoms. They were more prone to cognitive decline, psychosis and frontal lobe tissue loss by late adolescence, when schizophrenia symptoms begin to emerge, found the study, which was funded by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) and the National Institute on Child Health and Human Development (NICHD).
