The paternal age is a factor in schizophrenia because of the increased likelihood of mutations in the chromosomes of cells that produce sperm. (wikipedia.org)
The chance of a copying error in DNA replication during cell division increases with the number of cell divisions, and an increase in copying errors may cause an accumulation of mutations that are responsible for an increased incidence of schizophrenia. (wikipedia.org)
Important segregation should be made between lower risk, common variants (identified by candidate studies or genome-wide association studies) and high risk, rare variants (which could be caused by de novo mutations) and copy-number variations (CNVs). (wikipedia.org)
Scientists suggest that random genetic mutations during sperm production might explain the association. (todayonline.com)
This argument is often trotted out in discussions of the genetic architecture of schizophrenia, which centre on the question of whether it is caused by rare, single mutations in most cases or whether it is due to unfortunate combinations of thousands of common variants segregating in the population.
