Most infants have a cleft lip and cleft palate and low-set ears . Hernias and genital abnormalities are common. Trisomy 13 mosaicism and partial trisomy 13 also occur. Parents of infants with translocation type trisomy 13 should also have translocation studies. Because of the severity of congenital defects, life-sustaining procedures are generally not attempted.
Complications begin almost immediately.
Call for an appointment with your health care provider if you have had a child with Trisomy 13 and you plan to have another child. Surgical techniques used for cleft lip and palate repair provide excellent cosmetic results. Initial closure is accomplished in the first month. Extra digits may be present as an isolated finding, or they may occur as part of a syndrome, in which case other abnormalities are usually present. The most common form of polydactyly is an extra little finger.
