2. Rooted in Genetics: The Role of DNA in Cleft Lip
When it comes to understanding the origins of a cleft lip, genes often come into the spotlight. Like many other conditions, a cleft lip can be passed down through generations, laying testament to the power of our DNA. Though it’s not solely a genetic condition, inheriting certain gene combinations can increase the likelihood of a child being born with a cleft lip.
Researchers have identified several genes that, when mutated or combined in a specific way, can lead to the development of a cleft lip. However, it’s not a straightforward ‘inherit and manifest’ situation. Environmental factors during pregnancy, like exposure to certain drugs or infections, can influence its manifestation even when the genes are present.(2)
