What conditions/defects have approximately a 1/1000 incidence in the general population?

Cleft lip/cleft palate and hypospadias are conditions that are recognized to have an incidence of around 1 in 1,000 live births in the general population. Cleft lip and cleft palate are among the most prevalent congenital anomalies, impacting oral and facial development, while hypospadias is a common congenital condition affecting the male urethra. The recognition of these specific conditions with this incidence rate helps in providing genetic counseling and risk assessment for families, and it is significant in a clinical setting where understanding population-based prevalence is essential.

Other choices contain conditions that either have a higher or lower incidence or are not typically used in the same context for genetic counseling incidence statistics. Congenital heart disease, for instance, has a higher overall incidence than 1 in 1,000, while molar pregnancy does not fit the typical framework of congenital malformations assessed in such a community health context. Hence, the cleft lip/cleft palate and hypospadias pairing stands out based on their well-documented epidemiological data.
