Understanding the Genetic Incidence of Cleft Lip and Palate – Q&A with the Director at Misou Plastic Surgery

Cleft lip and palate are congenital conditions that affect many individuals worldwide. In Episode 7 of the Q&A series at Misou Plastic Surgery, the director sheds light on the genetic factors contributing to these conditions. Here’s a detailed guide to the discussion:

What Are Cleft Lip and Palate?

Cleft lip and palate occur when a baby’s lip or mouth does not form properly during pregnancy. This condition can involve:

• A split in the lip (cleft lip).
• An opening in the roof of the mouth (cleft palate).
• A combination of both.

The Genetic Connection

• Inheritance Patterns: Cleft lip and palate can run in families, with a multifactorial inheritance pattern involving both genetic and environmental factors.
• Risk Factors:
  • A parent with a cleft lip or palate may increase the likelihood of passing it on to their children.
  • Mutations in specific genes, such as IRF6, PAX9, or MSX1, are commonly associated.
• Ethnic and Regional Variations: Genetic predisposition may vary across populations, with some ethnic groups having higher incidence rates.

Environmental Influences

While genetics play a significant role, environmental factors such as maternal smoking, certain medications, and nutritional deficiencies during pregnancy can also contribute to the risk.

Q&A Highlights with the Director

1. What percentage of cleft lip and palate cases are genetic?
   • The director explains that approximately 20–30% of cases have a direct genetic link.
2. Are there tests to determine genetic risk?
   • Yes, genetic counseling and testing can help assess risks for prospective parents.
3. What can families do to reduce risks?
   • Prioritize prenatal care, avoid harmful substances, and consult a specialist if there’s a family history.
