Research Data

What are the facts?

Facts: 2/3 of translocation occurs spontaneously during fertilization. The majority of DS cases are not hereditary and Down Syndrome is not contagious.There are no cures because DS cannot be prevented and no one knows why and how this happens.DS is affects about 1 in every 800 babies that are born in the U.S.Women who are 35 and older are at a higher risk of having a child with the conditionat age 30, a woman has about a 1 in 1,000 chance of conceiving a child with DS while the odds increase at age 35 to 1 in 400 and at age 40 it becomes 1 in 100.

A developemental disorder caused by an extra copy of chromosome 21The extra chromosome may mean that each gene may be producing more protein product than normalThe extra chromosome comes from nondisjunction; when a pair of number 21 chromosomes fails to seperate during the formation of an egg (or sperm)This is also an autosomal disorderThere are a lot of physical characteristics and developmental delays associated with Down SyndromeSeveral health conditions associated with Down Syndrome are: Congenital Heart Defect, Pulmonary Hypertension, Hearing, Vision( cross-eyed, near or far-sighted, and an increased risk or cataracts), and there are tons of other conditions that deal with the endocrine system, digestive, how the kids talk an smell, seizures and last but not least Leukemia.Due to the possible health complications associated with Down Syndrome this is what makes the life expectancy age 50 for children who grow up with DS which basically means this disease isn't life ending but can lead to shorter life

Symptoms include: being shorter than average; having a short, wide neck and short, stocky arms and legs; a wide space in between their big and second toe; a single crease across the center of their palm (Tranverse Palmer crease); slower growing rate and learning rates; upward slant in their eyes, small ears, a protruding tongue, and a flat face They show physical signs of the disease in the womb but they are able to be seen at birth and then due to certain tests while in the womb DS can be detected or diagnosedThe treatments that can be offered are treatments of the symptoms whether they are physical or dealing with the abilities of the child such as speech, intellectual learning, and more.
