Down’s syndrome is a genetic disorder. It is caused by presence
of an additional chromosome 21. Down syndrome occurs because of an abnormality
characterized by an extra copy of genetic material on all or part of the 21st
chromosome. Every cell in the body contains genes that are grouped along
chromosomes in the cell's nucleus or center. There are normally 46 chromosomes
in each cell, 23 inherited from your mother and 23 from your father. When some
or all of a person's cells have an extra full or partial copy of chromosome 21,
the result is Down's syndrome.

Usually they can be easily recognized by their distinct
facial features like teddy bear like appearance, wide placed, slanted eyes,
flat nose, short stature etc.
Most of chromosomal abnormality occurs in pregnancy where the
maternal age is more. Kids with Down’s syndrome may suffer from congenital
heart issues, hearing and speech difficulties, thyroid dysfunctions, slow
physical growth leading to obesity.
Down’s
syndrome can be detected through tests during 4th or 5th
month of pregnancy or usually at time of birth. But in cases wherein the
maternal age is more, doctors now-a-days usually suggest various tests in 1st
4 months of pregnancy to rule out any kind of abnormalities.
Kids
with Down’s syndrome need regular follow-ups with their pediatric doctor and
cardiologist to rule out any kind of problems and also therapies to develop their
cognitive skills. Kids with Down’s syndrome need special schooling and vocational
training.
