Paternal-Age-Related de Novo Mutations and Risk for Five Disorders

Epidemiologic associations have been made between advanced paternal age and increased offspring risk of autism spectrum disorder (ASD), schizophrenia (SCZ), congenital heart disease (CHD), epilepsy (EPI), and intellectual disability (ID). This association have been often attributed to de novo single nucleotide variants (dnSNVs) that occur 3 to 4 times more often in paternal compared with maternal germ cells.
