Overview:
Rehabilitation Council of India (RCI), New Delhi, celebrated World Down Syndrome Day by organizing a free Webinar open for all, in association with the Down-Syndrome Federation of India.
About Dawn syndrome:
- Dawn syndrome is a genetic disorder, caused by the presence of an extra chromosome 21 also known as trisomy of chromosome 21.
- It is one of the leading causes of genetic disorders around the world.
- Types of Down syndrome: There are three types of Down syndrome.
- Trisomy 21: About 95% of people with Down syndrome have Trisomy 21. With this type of Down syndrome, each cell in the body has 3 separate copies of chromosome 21 instead of the usual 2 copies.
- Translocation Down syndrome: This type accounts for a small percentage of people with Down syndrome (about 3%). This occurs when an extra part or a whole extra chromosome 21 is present, but it is attached or “trans-located” to a different chromosome rather than being a separate chromosome 21.
- Mosaic Down syndrome: Mosaic means mixture or combination. For children with mosaic Down syndrome, some of their cells have 3 copies of chromosome 21, but other cells have the typical two copies of chromosome 21.
- The primary symptoms of Down’s Syndrome are as follows:
- Mental retardation
- Cognitive impairment may be mild to moderate
- Tilted eyes or Fold of the skin above the eye etc.
- Treatment: Down syndrome is a lifelong condition and it cannot be cured. Early therapy programs can help improve skills.

Q1) What is genetics?
Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
