Trisomy 13 is the most common cause of holoprosencephaly, which causes severe abnormalities of midine facial structures[14]. Patau's syndrome is a serious rare genetic disorder caused by having an additional copy of chromosome 13 in some or all of the body's cells. Rasmussen SA, Wong L-YC, Yang Q, May KM, Friedman JM. Beispiele: [1] Mit Ausnahme der gonosomalen Trisomien und der Trisomie 21 sind Trisomien in der Regel nicht mit dem Leben vereinbar und führen zu frühen Fehlgeburten oder dem Tod des Neugeborenen in den ersten Lebensmonaten und -jahren.

Trisomy 13, also known as Patau Syndrome, is a disorder of fetal development with wide-ranging and often severe developmental manifestations. These babies must battle complications of prematurity as well as other symptoms of trisomy 13.; Facial abnormalities: Many babies with trisomy 13 are born with a cleft lip and/or a cleft palate. The physical features of mosaic trisomy 13 and partial trisomy 13 are often milder than those of full trisomy 13, resulting in more babies living longer. Carol M. Stenson, Steven E. Daley, Patricia A. Baty BJ, Jorde LB, Blackburn BL, Carey JC. Features: Midface abnormality - key feature. Postnatal diagnostic genetic testing may be undertaken if features of the syndrome are suspected in an infant who was not diagnosed in the prenatal period. Savva GM, Walker K, Morris JK.

Eye findings in the 13 trisomy syndrome. 75-80% of affected infants do not survive beyond the first month, with a higher fatality rate for males[2][29][30]. However, trisomy 13 can be inherited if a parent has a rearrangement of chromosome material that involves chromosome 13. Autosomal trisomy can be associated with birth defects, intellectual disability and shortened life expectancy. Common findings include microcephaly; cleft lip and palate; polydactyly; cutis aplasia; and cardiac, CNS, and genitourinary anomalies[6][11][13]. Trisomy 13, or Patau Syndrome, is a severe developmental disorder that results in developmental anomalies in multiple organ systems. Trisomy 13 most often occurs because of a random mistake in the division of egg or sperm cells.
