What are the risk factor of achondroplasia?

Achondroplasia is primarily caused by a genetic mutation in the FGFR3 gene and is mostly inherited in an autosomal dominant manner. The most significant risk factor is advanced paternal age, as older fathers are more likely to pass on the mutation. Additionally, having a family history of achondroplasia increases the risk of having affected children. Environmental factors do not play a significant role in the development of this condition.
