Down syndrome is a genetic disorder. It is also called trisomy It includes certain birth defects, learning problems, and facial features. with Down syndrome also may have heart defects and problems with vision and hearing. How severe or mild these problems are varies from child to child.
Down syndrome is one of the most common genetic birth defects. It affects about 1 in babies. Adults with Down syndrome may live about 60 years, but this can vary. When a baby is conceived, a normal egg cell and normal sperm cell start with 46 chromosomes. The egg and sperm cells then divide in half.
The egg and sperm cells then have 23 chromosomes each. When a sperm with 23 chromosomes fertilizes an egg with 23 chromosomes, the baby will then have a complete set of 46 chromosomes. Half are from the father and half are from the mother.
But sometimes an error occurs when the 46 chromosomes are being divided in half. An egg or sperm cell may keep both copies of chromosome 21, instead of just 1 copy. If this egg or sperm is fertilized, then the baby will have 3 copies of chromosome This is called trisomy Sometimes the extra 21 chromosome or part of it is attached to another chromosome in the egg or sperm.
This may cause translocation Down syndrome. This is the only form of Down syndrome that may be inherited from a parent. A rare form is called mosaic trisomy This is when an error in cell division happens after the egg is fertilized.
People with this syndrome have both normal cells and some cells with an extra chromosome This risk increases with each year of age, especially after age But younger women are more likely to have babies than older women. So most babies with Down syndrome are born to women younger than Chromosome problems such as Down syndrome can often be diagnosed before birth. This is done by looking at cells in the amniotic fluid or from the placenta.
This is a noninvasive prenatal screening. These tests are very accurate. Fetal ultrasound during pregnancy can also show the possibility of Down syndrome. Problems from Down syndrome may not be seen with ultrasound. After birth, your baby may be diagnosed with a physical exam.
The healthcare provider may also take a blood sample. This is checked in a lab to find the extra chromosome. There is no cure for Down syndrome.

Others may need surgery. All babies with Down syndrome should be looked at by a pediatric cardiologist. Babies with Down syndrome should also have an echocardiogram. This is a test that looks at the structure and function of the heart by using sound waves.
This exam and test should be done in the first 2 months of life. This is so that any heart defects can be treated. Intestinal problems. Some babies with Down syndrome are born with intestinal structure problems that need surgery. Vision problems. Common problems include crossed eyes, nearsightedness or farsightedness, and cataracts. Most eyesight problems can be made better with eyeglasses, surgery, or other treatments. Your child should see an eye doctor pediatric ophthalmologist before he or she turns 1 year old. Hearing loss.
