Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13. The extra genetic material disrupts normal development, causing multiple and complex organ defects.
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.
Although many children with holoprosencephaly have normal chromosomes, specific chromosomal abnormalities have been identified in some patients (trisomy of chromosome 13, also known as Patau syndrome). There is evidence that in some families, HPE is inherited (autosomal dominant as well as autosomal or X-linked recessive inheritance).
Patau may refer to: Klaus Patau , a geneticist who first reported Patau chromosome associated with Patau syndrome Patau chromosome , also known as Chromosome 13, associated with Patau syndrome
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
Detailed anthropological and sociological studies have been made about customs of patrilineal inheritance, where only male children can inherit. Some cultures also employ matrilineal succession, where property can only pass along the female line, most commonly going to the sister's sons of the decedent; but also, in some societies, from the mother to her daughters.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.
