Recurrent cleft lip and palate in siblings of a patient with malabsorption syndrome, probably caused by hypovitaminosis a associated with folic acid and vitamin B(2) deficiencies.

We present a woman with metabolic disorders secondary to malabsorption and renal disease who gave birth to a stillborn male fetus with left unilateral cleft lip and palate and a live born infant with left unilateral cleft lip and palate. We discuss potential cofactors that could be implicated in the abnormal embryonic process.
