What conditions/defects have approximately a 1/100 incidence in the general population?

The choice of molar pregnancy and epilepsy suggests a focus on two conditions with varying incidences in the general population, but the commonality to the question's 1 in 100 incidence threshold is not as strong as in other options presented.

When considering congenital disorders and their prevalence, congenital heart disease and cleft lip are known to have incidences that approach or exceed this figure. Cleft lip, for instance, occurs in about 1 in 1000 births, which when combined with other congenital issues like congenital heart defects—which also have a significant prevalence—often features prominently in discussions of common defects.

On the other hand, epilepsy does have a higher prevalence in the general population, affecting about 1 in 100 people, which contributes to its association with the 1 in 100 incidence. However, molar pregnancy typically has a much lower incidence, around 1 in 1,000 to 1 in 2,000 pregnancies, thus failing to meet the criteria set forth in the question.

The combination of congenital heart disease and cleft lip provides an illustrative example of conditions meeting or exceeding a 1 in 100 incidence, setting it apart as a more fitting selection in this context. Therefore, understanding epidemiology and
