diseases you are born with
People born with kidney dysplasia have both kidneys; however, one kidney does not function (top right). When a kidney is removed surgically due to disease or for donation, both the kidney and ureter are removed (bottom right).
Down syndrome is a relatively common birth defect, affecting about 1 in 800 to 1,000 births. The chances of having a baby with Down syndrome increase dramatically with the age of the mother. Children with Down syndrome are born with an extra (third) copy of chromosome number 21 in their cells.
