Detailed explanation-1: -Intensive DNA search yields 10 genes tied directly to schizophrenia.
Detailed explanation-2: -The Psychiatric Genomics Consortium (PGC) paper found a much larger number of genetic links to schizophrenia than ever before, in 287 different regions of the genome.
Detailed explanation-3: -Deletions or duplications of genetic material in any of several chromosomes, which can affect multiple genes, are also thought to increase schizophrenia risk. In particular, a small deletion (microdeletion) in a region of chromosome 22 called 22q11 may be involved in a small percentage of cases of schizophrenia.
Detailed explanation-4: -Chromosome 22q11. 2 microdeletions provide the most convincing evidence of an association between a molecular cytogenetic abnormality and schizophrenia.
