21 March adalah Hari Down Sindrom.
What is Sindrom Down?
In every cell in the human body there is a nucleus, where genetic
material is stored in genes. Genes carry the codes responsible for all
of our inherited traits and are grouped along rod-like structures called
chromosomes. Typically, the nucleus of each cell contains 23 pairs of
chromosomes, half of which are inherited from each parent. Down syndrome
occurs when an individual has a full or partial extra copy of
chromosome 21.
This additional genetic material alters the course of development and
causes the characteristics associated with Down syndrome. A few of the
common physical traits of Down syndrome are low muscle tone, small
stature, an upward slant to the eyes, and a single deep crease across
the center of the palm - although each person with Down syndrome is a
unique individual and may possess these characteristics to different
degrees, or not at all.
