How Does A Baby Develop Down Syndrome?

Down Syndrome is a genetic disorder that affects approximately 1 in every 700 babies born in the United States. It is caused by the presence of an extra chromosome 21, which leads to developmental delays and intellectual disabilities. In this blog post, we will discuss how a baby develops Down Syndrome.

What Causes Down Syndrome?

Down Syndrome is caused by a genetic mutation that occurs during cell division in the mother’s womb. Normally, humans have 23 pairs of chromosomes, or a total of 46 chromosomes. However, in the case of Down Syndrome, there is an extra copy of chromosome 21, resulting in a total of 47 chromosomes.There are three types of Down Syndrome, including Trisomy 21, Mosaicism, and Translocation. Trisomy 21 is the most common type, accounting for about 95% of all cases. It occurs when there is an extra copy of chromosome 21 in every cell of the body. Mosaicism occurs when there is a mixture of cells, some with 46 chromosomes and others with 47. Translocation occurs when part of chromosome 21 breaks off and attaches to another chromosome.

When Does Down Syndrome Develop?

Down Syndrome develops during the early stages of fetal development. It is not caused by anything the mother did or did not do during her pregnancy. The extra chromosome 21 can come from either the mother or the father, and it is usually a random occurrence.

There are two types of prenatal testing available, including screening tests and diagnostic tests.Screening tests, such as the first trimester screening and the quad screen, can indicate whether a woman is at higher risk of having a baby with Down Syndrome. However, these tests are not definitive and can result in false positives and false negatives.Diagnostic tests, such as chorionic villus sampling (CVS) and amniocentesis, can confirm whether or not a baby has Down Syndrome. These tests are more invasive and carry a higher risk of miscarriage, so they are usually only recommended for women who are at high risk of having a baby with the condition.

Can Down Syndrome Be Treated?

Early intervention programs, such as speech and physical therapy, can help children with Down Syndrome reach their full potential.
