Down's
Syndrome is a genetic disorder due to the presence of an extra
chromosome 21.
There
are three types
of chromosome abnormalities:
1)
Trisomy 21
2)
Translocation
3)
Mosaicism
Some of the
physical features
in children with Down's syndrome are: slanting
of the eyelids, decreased muscle tone, loose ligaments, smaller ears,
mouth, hands and feet.
50%
of children have one line across the palm (it's a gap between the
first and second toes).
The
cause is still unknown. There isn't a cure available at the present
time.
Well done!
