The exact cause of cleft lip and palate is not known, but it is believed to be a combination of genetic and environmental factors. Some possible causes include:
1. Genetic factors: Cleft lip and palate can run in families, suggesting a genetic component. Certain genetic mutations or variations may increase the risk of a baby being born with a cleft lip or palate.
2. Environmental factors: Exposure to certain environmental factors during pregnancy, such as smoking, alcohol consumption, certain medications, or infections, may increase the risk of a baby being born with a cleft lip or palate.
3. Folic acid deficiency: A lack of folic acid (a B vitamin) during pregnancy has been linked to an increased risk of cleft lip and palate in babies.
4. Other factors: Other factors that may contribute to the development of cleft lip and palate include maternal age, maternal health conditions (such as diabetes), and certain prenatal exposures.
It is important to note that in many cases, the exact cause of cleft lip and palate is not known, and it is likely a combination of genetic and environmental factors.

Genetic Factors:
- Mutations or genetic variations in genes responsible for facial development, such as TBX1, FOXA2, and OTX2 - Chromosomal abnormalities, such as trisomy 13 and 21
Environmental Factors:
- Maternal smoking: Nicotine and other chemicals in cigarettes interfere with fetal development. - Alcohol consumption during pregnancy: Ethanol damages developing fetal cells. - Certain medications: Some medications, such as valproic acid and phenytoin, taken during pregnancy can increase the risk of cleft lip and palate. - Nutritional deficiencies: Folic acid, vitamin B12, and iron deficiencies during pregnancy have been linked to an increased risk. - Maternal infections: Certain infections, such as rubella and cytomegalovirus, can cause fetal malformations, including cleft lip and palate.
Other Factors:
- Family history: Having a parent or sibling with cleft lip and palate increases the risk for a child. - Facial clefts tend to occur more frequently in certain ethnic groups. - Low birth weight and prematurity.
Multifactorial Cause:
Cleft lip and palate is often considered a multifactorial condition, meaning that it is caused by a combination of genetic and environmental factors.
