Key points

  • Clefts of the lip and palate are the most common types of birth defects, occurring in about one in every 1,000 births.
  • In most children, clefts happen because of a mix of genetic and environmental factors.
  • Your child's geneticist is a medical doctor who specializes in genetics.
  • For parents of children with a cleft lip and/or palate, understanding genetics is important because some syndromes associated with clefts can be passed from parent to child.
