What are the common findings in trisomy 13?
Infants born with Trisomy 13 can have structural abnormalities of the brain and face, which often include facial clefting. Problems with the structural formation of the heart, extra fingers and toes (polydactyly), and effects on many other organ systems can be seen. Mental retardation is usually severe, and the average lifespan of these children is severely compromised.
