 Genetic Disorders: The Links to Diet
The old school of thinking that a birth defect or inherited disorder had to be caused by a single gene is no longer widely held in medical circles.
The breakthrough concept in research is that many birth defects and inherited disorders are influenced by both genes and environmental factors, especially nutrition.
Many other disorders that were once thought to be caused by single genes may actually be the results of a complex set of factors involving both nutrition and genes.

 UTHSC researchers map gene for rare inherited disorder
In real life, however, gene research is hard work focusing on the prevention of inherited disorders.
Specifically, gene mapping, a powerful technique used in modern molecular genetics, helps identify unknown genes in families with a particular inherited disorder, which includes many psychiatric diseases.
The challenge is to look in that region of the chromosome indicated by the mapped marker and identify the exact gene, and then a mutation, that’s responsible for the disease in a given family.

 Greig Cephalopolysyndactyly Syndrome
Greig Cephalopolysyndactyly Syndrome, a very rare inherited disorder that is present at birth (congenital), is characterized by abnormalities of the fingers and toes (digits) and the head and facial (craniofacial) area.
For example, some cases where Greig Cephalopolysyndactyly Syndrome was inherited as a dominant trait, the disorder was shown to result from a balanced chromosomal translocation in one of the parents involving chromosome 7p13.
In this disorder, the polydactyly is considered preaxial; that is, the extra digit or digits are toward the thumb side of the hand and the great toe side of the foot.

 || DukeMedNews || Gene With Broad Role Also Causes Prevalent, Inherited Nerve Disorder
The disorder affects approximately 1 in every 2,500 people, making it one of the most common of all hereditary disorders, said the researchers.
Their findings also reveal a previously unknown link between CMT and a deficiency of white blood cells, suggesting that defects in dynamin 2 might underlie both conditions, the researchers reported in the Jan. 30, 2005, issue of Nature Genetics.
As evidence mounts for the genetic basis of the disorder's different forms, scientists can begin to develop therapies to specifically target the root causes of CMT in particular families, added senior author Jeffery Vance, M.D., associate director of the Center for Human Genetics and professor of medicine at Duke.

Results showed that 1 in 50,000 babies are born with the SCADD inherited metabolic disorder.
The results of the recently carried out study, which found the SCADD disorder to be more popular among newborn babies than previously estimated may call for routine screening for the metabolic inherited disorder in infants.

 Penn Today Online: Jul/Aug 2002 - Vision Researchers Solve Rare Inherited Retinal Disorder
The posthumous donation of eyes from a patient with an inherited retinal disease, Enhanced S Cone Syndrome (ESCS) has taught researchers at Penn Eye Care at the Scheie Eye Institute more about ESCS and the role of NR2E3, the gene that causes this form of blindness.
ESCS, a member of the retinitis pigmentosa (RP) family of inherited diseases of the retina, causes night blindness and increased sensitivity to blue light.
Researchers do not have a complete understanding of how rods and cones develop, but the death of these cells is a key component to many forms of inherited blindness, including RP and age related macular degeneration (AMD).
