Discover About the Chromosomal Abnormality Syndrome in Humans.
Commonly referred to as a genetic condition or a chromosomal condition that occurs when a child is born with an error in cell division or with an extra copy of the 21st chromosome. Is what we term Down Syndrome. Affecting more than thousands of people in the US, down syndrome is the most common chromosomal abnormality syndrome that has some mild to serious physical and developmental problems.
Down syndrome is a lifelong condition that has no treatment and is caused by an extra chromosome. In general whenever a mother starts to conceive and the infant starts to grow the cells in the body of the baby have 23 chromosomes each pair from the mother and the father. But in down syndrome, some changes occur in a cell and the child gets an extra copy of chromosome 21 resulting in three copies instead of two.
As per Dr. Elsa, a Gynaecology Surgeon in Dubai, people with down syndrome are living an improved, longer, and richer life than ever. They often face challenges but have the willpower to overcome those all because of their parents and families.

- Mosaicism: Affecting people in the rarest case Mosaicism down syndrome is that type under which the child has an extra chromosome in some cells of their body.
