Overview
Down syndrome is one of the most common genetic disorders seen in children. It occurs when the child is born with an extra chromosome. Chromosomes are thread-like structures found in every cell of the body. They carry hereditary information in the form of genetic codes. The presence of an extra chromosome in a child can affect the development of the baby’s body and brain, leading to birth defects, learning problems, and abnormal facial features.
 
The risk of a baby being born with Down syndrome is slightly high in women who conceive at or after 35 years. A 35-year-old woman has a 1 in 350 chance of conceiving a baby with Down syndrome. Routine antenatal (pregnancy-related) screening tests can help detect the condition early in the pregnancy (first trimester). 
 
Down syndrome is a lifelong condition. Currently, there are no approved medicines available for its treatment. Medical treatment is driven symptomatically based on the comorbidities affecting the individual. This helps to improve the quality of life and also helps increase life expectancy of the person.
