It's located on the X chromosome.
Chromosome 21 is tripled in Down syndrome.
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
"Autosomal" means the syndrome or disorder of interest is pertaining to a chromosome that is not a sex chromosome, either X or Y. Angelman and Prader-Willi Syndrome are both caused by a deletion (or disruption of a gene) on chromosome 15, which is an autosomal chromosome and not a sex chromosome. Therefore, yes, Angelman syndrome is considered an autosomal syndrome.
Down syndrome occurs because of the extra chromosome on chromosome 21. If you go onto google images and type in karyotype of Down syndrome, you will find a picture of the extra chromosome. Instead of having two chromosomes on chromosome 21, there is an extra. Type your answer here...
Nail Patella Syndrome is found on chromosome #9. If you search "what chromosome is nail patella syndrome on?" in Google, then it will give you a bunch of websites that have a bunch of info. about it. hope this helps. :-)
No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
Meckel Syndrome (type 1)is an autosomal recessive trait carried on chromosome 17.
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
The three major chromosomal disorders are Down syndrome, Turner syndrome, and Klinefelter syndrome. Down syndrome is characterized by an extra copy of chromosome 21, Turner syndrome involves a missing or incomplete X chromosome in females, and Klinefelter syndrome is caused by an extra X chromosome in males.
