US scientists say they have “fundamentally transformed” the understanding of the genetics of schizophrenia.
A report in the journal Nature Genetics showed that “fresh mutations” in DNA are involved in at least half of schizophrenia cases, when there is no family history of the illness.
Researchers found mutations in 40 different genes.
They say their findings explain the high number of cases around the world.
