BACKGROUND: Maternal smoking is a known risk factor for orofacial clefts. We investigated whether risk is greater among offspring who lack the genetic capacity to produce glutathione S-transferase enzymes relevant to detoxification of chemicals in cigarette smoke. METHODS: Using a population-based case-control design, we genotyped 423 California infants with an isolated cleft and 294 nonmalformed controls for...
