Trisomy 13 (Patau syndrome) with an 11‐year survival

Abstract
Trisomy 13 is very rare in live‐born children. Only a small number of these children survive the first year and very few cases are reported to live longer. Survival time depends partly on the cytogenetic findings ‐ full trisomy 13 or trisomy 13 mosaicism ‐ and partly on the existence of serious somatic malformations. We report on a 11‐year‐old girl with full trisomy 13. In this case, missing cerebral and cardiovascular malformations probably allowed the long survival.
