Harelip can be inherited, but not all harelip patients are caused by genetics; it can also be caused by other reasons.
Harelip is a congenital malformation with hereditary properties. Similar malformations can occur in the immediate or collateral relatives of harelip patients, and may also be inherited intergenerationally, but the chances of inheritance are not high. In addition, dietary and organic factors may also lead to the occurrence of harelip, such as smoking and drinking habits during pregnancy, low vitamin intake, viral infections, medication, long-term exposure to chemical substances or physical radioactive substances, all of which may affect the abnormal development of the fetus and lead to harelip.
Due to the presence of genetic factors, family members with a history of harelip should have a good premarital examination for early prevention and treatment. Pregnant women should pay attention to their diet and avoid exposure to radioactive substances during pregnancy.
