Vanishing Twin is: More common than isolated cleft palate. Vt may occur in up to 30% of multiple gestations, but we are detecting this more frequently because of better tests. Cleft palate incidence differs among races, but occurs in about 0.5 births per 1000. CP is most common in american indians, then japanese, chinese, whites, and blacks. CP has a genetic basis whereas twin births generally do not.
