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 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.

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. 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.
