Down syndrome is a genetic disorder that is caused by abnormal cell division. Human cells normally contain 23 pairs of chromosomes, half of each pair from the father and the other half from the mother. People with Down syndrome have extra genetic material in chromosome 21, causing the developmental problems and features of Down syndrome. In most cases, the individual has a third chromosome 21 in all cells, this is called Trisomy 21. However, there are also two other forms of Down syndrome that are rare. Some may have some cells with an extra copy of chromosome 21 and have a form called Mosaic Down syndrome. Translocation Down syndrome is the third form; it can be passed from parent to child, however only about 4% have this form of Down syndrome. These individuals can have the usual two copies of chromosome 21, but have additional material connected.

I found this really interesting and well written. I had a relative of mine who had Downs Syndrome but I was too young to know much about her. I think it is intriguing how this disorders severity varies so much. How and why some can be so high functioning, while others are more reliant on caregivers. The relative I had (Helen) benefited greatly from eventually going to a school that was to help her and she loved going and thrived. She grew up in the days of being kept away from others.Once other relatives got involved and learned more about Downs Syndrome, they realized how beneficial her school was for her.

I agree it is very interesting to see how the disorder can affect people, I grew up around children who could barely speak and needed someone with them 24/7, then grew up around some who are able to do almost everything on their own. I feel that some schools do an excellent job with special needs children and it's great it was beneficial for your cousin!

There are two forms of Hemophilia. There is type A (classic hemophilia, or factor VIII deficiency) or there is type B (Christmas disease, or factor IX deficiency) Hemophilia A is a hereditary bleeding disorder caused by a lack of blood clotting factor VIII. This is caused by caused by an inherited X-linked recessive trait. The defective gene is located on the X chromosome. Females have two copies of the X chromosome so if one is not present often the other will produce enough of the VIII factor. Males have only one X chromosome which is why hemophilia A is most prevalent in males. There is usually a family history of hemophilia which is passed down usually to males.

The genetic disorder I chose to do was Multiple Sclerosis or more commonly known as (MS). Multiple sclerosis affects the brain and spinal cord. Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to communicate, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems.
