Orofacial clefts are thought to be determined by the interplay of genetic and environmental factors. Experiments on animals demonstrated that vitamin B12 supplemented diets antagonize selected teratogens during palatogenesis. Increased propionylcarnitine in neonates is regarded as a marker of maternal vitamin B12 deficiency. The retrospective study was undertaken to determine whether increased propionylcarnitine in newborns is associated with orofacial clefts. Fifty‐two newborns with isolated cleft lip with or without cleft palate (CLP) and 107 control newborns without congenital anomalies were investigated. Whole blood propionylcarnitine concentrations were measured using tandem mass spectrometry. The mean concentrations of propionylcarnitine in newborns with clefts and controls were 2.82 ± 1.06 µ mol L −1 and 2.68 ± 0.94 µ mol L −1 , respectively. T ‐test for equality of means did not confirm any significant differences between both groups ( P = 0.381). Deficiency of vitamin B12 with metabolic disturbances seems not to be a risk factor for CLP in the investigated group of patients.
