Advanced paternal age is clearly associated with an increased risk of new mutations.

Examples of new mutant conditions associated with
advanced paternal age include

achondroplasia (a frequent form of dwarfism), neurofibromatosis (NF1),
Marfan syndrome,
Treacher Collins syndrome,
Waardenburg syndrome (a common cause of deafness),
osteogenesis imperfecta (brittle bone disease)
Apert syndrome (a form of acrocephalosyndactyly with an abnormally tall skull, shallow eye sockets, and fusion of fingers and toes).
