GENETICS IN A NUTSHELL
Genetics involves the division of cells or the
chance of offspring inheriting certain features
from genes which can include biological disease.

Cellular division a DNA job!
Cellular division is the division of cells in a
microscopic level. Cells must divide so that
tissue can be repaired, blood can be produced,
and you can grow.Cellular division is properly
the most important job of anything in the body
save DNA. DNA is needed for cell division because
without it the divided cells would only have half
the genes and chromosomes.

ACHONDROPLASIA

What is achondroplasia
Achondroplasia is a genetic disorder of bone
growth that is evident at birth. It affects about
one in every 25,000 births and it occurs in all
races and in both sexes. Its depiction in ancient
Egyptian art makes it one of the oldest recorded
birth defects.It is the most common of a group
of growth defects characterized by abnormal body
proportions affected individuals have arms and
legs that are very short, while the torso is more
nearly normal size. The word achondroplasia is
derived from Greek and means "without cartilage
formation," although individuals with
achondroplasia do have cartilage. During fetal
development and childhood, cartilage normally
develops into bone, except in a few places, such
as the nose and ears.

What does achondroplasia look like?
A child with achondroplasia has a relatively
normal torso and short arms and legs. The upper
arms and thighs are more shortened than the
forearms and lower legs. Generally, the head is
large, the forehead is prominent and the nose is
flat at the bridge. Sometimes, the large head
size reflects hydrocephalus (excess fluid in the
brain), and require surgery.

Before beginning to walk, a baby with
achondroplasia often develops a small hump
(kyphosis) on his upper back. This is due to poor
muscle tone, and usually goes away after the
child starts walking.
How does achondroplasia affect development?
Babies with achondroplasia should not be placed
in umbrella-type strollers or other carriers that
do not provide good back support, because lack of
support can contribute to development of a hump
in the back. Once walking, the child usually
develops a markedly curved lower spine (lordosis
or sway- back), and the lower legs often become
bowed. The feet are generally short, broad and
flat.
