Trisomy 18, also known as Edwards syndrome, is a genetic disorder caused by the presence of a third copy of all or part of chromosome 18. [3] Many parts of the body are affected. [3] Babies are often born small and have heart defects. [3]
Trisomy 18 is a fatal chromosomal condition that can be detected during pregnancy.It's also at the center of a new legal case in Texas, where a mom of two, Kate Cox, is seeking an abortion after ...
Klaus Patau (30 September 1908 – 30 November 1975; born Klaus Pätau; pronounced [ˈklaʊs ˈpɛtaʊ]) was a German-born American geneticist.He received his PhD from the University of Berlin in 1936, worked from 1938 to 1939 in London, and then returned to Germany, where he worked at the Kaiser Wilhelm Institute for Biology until 1947.
Trisomy 13 is the cause of Patau syndrome, which means each cell in the body has three copies of chromosome 13 instead of the usual two. A small percentage of cases occur when only some of the body's cells have an extra copy; such cases are called mosaic trisomy 13. [citation needed]
Trisomy 18 typically results in life-threatening complications for a baby, but one little girl, Georgia, is proof of how one can live with it. Living with trisomy 18: How a 6-year-old girl is ...
Karyotype of a human with Trisomy 21 (Down syndrome). Trisomies can occur with any chromosome, but often result in miscarriage rather than live birth.For example, Trisomy 16 is most common in human pregnancies, occurring in more than 1%, but the only surviving embryos are those having some normal cells in addition to the trisomic cells (mosaic trisomy 16).

A Robertsonian translocation in balanced form results in no excess or deficit of genetic material and causes no health difficulties. In unbalanced forms, Robertsonian translocations cause chromosomal deletions or addition and result in syndromes of multiple malformations, including trisomy 13 (Patau syndrome) and trisomy 21 (Down syndrome). The ...
By the 19th century, theories which were based on the belief that Jesus was a member of the so-called "Aryan race", and in particular, theories which were based on the belief that his appearance was Nordic, were developed and later, they appealed to advocates of the new racial antisemitism, who did not want to believe that Jesus was Jewish ...
