There are many offspring of older dad who suffer genetic disorders due to the paternal age effect. Paternal age effect From Wikipedia, the free encyclopedia Jump to: navigation, search The paternal age effect describes the influence that a father's age has on the chances of conferring a genetic defect to his offspring. Generally, older men have a greater probability of fathering children with a genetic defect than younger men do. This is seen as likely due to genetic copying errors which may increase in number after repeated spermatogenesis cycles over a man's lifetime. [edit] Disorders correlated with paternal age Achondroplasia (dwarfism); craniofacial disorders such as Apert syndrome and Crouzon Syndrome; mental retardation of unknown etiologies; autism; bipolar disorder; and 25% of schizophrenia cases are correlated with advanced paternal age. Other disorders related to advanced paternal age are: Wilms' tumor Thanatophoric dysplasia Retinitis pigmentosa Osteogenesis imperfecta type IIA Acrodysostosis Fibrodysplasia ossificans progressiva Aniridia Bilateral retinoblastoma Multiple exostoses Marfan syndrome Lesch-Nyhan syndrome Pfeiffer syndrome Wardenburg syndrome Treacher Collins syndrome Soto's basal cell nevus Cleidocranial dysostosis Polyposis coli Oculodentodigital syndrome Costello syndrome Progeria Recklinghausen's neurofibromatosis Tuberous sclerosis Polycystic kidney disease Hemophilia A Duchenne muscular dystrophy Athetoid cerebral palsy Dystonic cerebral palsy Congenital hemiplegia Down syndrome Bipolar disorder [edit] References Crow JF (1997).
