What caused Cleft Lip/Cleft Palate to occur in my child?

The condition is due to multiple factors. Cleft lip with or without a cleft palate can be an inherited condition, but more commonly is the result of a developmental break in the fusion of the facial segments. Exposure to heavy metals, deficiencies of vitamin B12 and folate, and environmental factors can all play a part in causing these deformities. The condition can be associated with more complex facial syndromes but is less common than singular presentation alone.
