45 views

Individuals most at risk of having Down syndrome are children born to mothers over the age of 35. The likelihood increases with maternal age, due to higher chances of genetic anomalies in the eggs of older women. Fathers over 40 may also contribute to an increased risk, albeit to a lesser extent. Advanced parental age is therefore a significant factor in the likelihood of a child being born with Down syndrome.
