What diseases are found in chromosomes?

Answer 1

* Down Syndrome -- an extra 21st chromosome

* Angelman Syndrome -- an absence of chromosome #15 in the brain

* Fragile X Syndrome -- a deficiency in one of the x chromosomes

* Rett Syndrome -- deletion of an entire x chromosome (mainly strikes females)

* Patau Syndrome -- tripling of chromosome #13 (infants appear mutilated)

Answer 2

I don't know that diseases are found in chromosomes. However, a deleted chromosome or an extra chromosome causes significant conditions for the person. In Turner syndrome, the female has one X instead of two X chromosomes. An extra chromosome 21 (three instead of two) causes Down's syndrome. Klinefelter's results when the male has an extra X chromosome, Trisomey 13, and trisomey 18 also have significant consequences.

Other conditions are the result of single gene mutation within a chromosome such as hemophilia, muscular dystrophy, sickle cell anemia, cystic fibrosis and many others.

Some examples include the Wolf-Hirschhorn syndrome, Jacobsen syndrome, Charcot-Marie-Tooth disease type 1A

This is not intended to be an exhaustive list of genetic abnormalities. I merely listed some of the more common. As knowledge progresses, we may find many genetic links.
