There is now increasing evidence that dyslexia could be something of a genetic disorder. A new discovery has located yet another gene variant that could be partly to blame for poor reading ability.

Anencephaly, a rare birth defect, has a genetic cause. The gene responsible for anencephaly has been discovered in mice, opening up the door to genetic testing and therapies for this genetic disorder.

The 2008 Nobel Prize for Chemistry was awarded to two American scientists and a Japanese researcher for their work on exploiting the genetic mechanism responsible for luminosity in some marine creatures. Their revolutionary studies have helped to shed light on many different biological systems.

Barbara McClintock (1902-1992), who focused on maize genetics, studied the transposition of genes on chromosomes during breeding. McClintock won awards throughout her career, culminating in the 1983 Nobel Prize in Physiology or Medicine. Her insights were decades ahead of many of her contempories.

Kartagener’s syndrome is a rare genetic disorder also known as PCD. What causes it? What are the symptoms? How is PCD treated? Find out below.

Colorectal cancer is a major disease of both men and women. The cancer takes several years to develop and usually starts with a small lump or growth. For up to 10% of cases, colorectal cancer is a genetic disease. This article is an overview of the genes involved.

One of the world’s most famous geneticists, Francis Crick was the joint winner of the Nobel Prize for Physiology in 1962 for his work on revealing the structure of DNA. It was a discovery that changed humanity’s view of itself and of the natural world.

Genetic disorders come in a variety of forms. This article looks at how the possession of an extra chromosome produces a genetic disorder known as Klinefelter’s syndrome.

Hemophilia is a genetic disorder that restricts the body’s ability to clot blood. In its most severe form even something as trivial as a minor injury can lead to death.
