  Blood disorder - The basics of Hemochromatosis: Always-Health.com   (Site not responding. Last check: 2007-11-04)
Hereditary hemochromatosis is an autosomal recessive blood disorder associated with increased intestinal absorption of iron and deposition of excessive amounts of iron in the vital organs of the body like the liver, pancreas, and other organs.
Among US white population, this disorder is the most common single-gene disorder with approximately one in every 250 to 300 white persons is susceptible for the hemochromatosis gene mutation, and at least one in 10 persons is a carrier for the mutation.
Hereditary hemochromatosis is a hereditary health disorder which is passed from parents to children through the HFE gene whose sole responsibility is to make the body store too much iron.

 Hereditary Fructose Intolerance | AHealthyMe.com
Hereditary fructose intolerance is an inherited condition where the body does not produce the chemical needed to break down fructose (fruit sugar).
Fructose intolerance is a disorder caused by the body's inability to produce an enzyme called aldolase B (also called fructose 1-phosphate aldolase) that is necessary for absorption of fructose.
Since this is a hereditary disorder, there is currently no known way to prevent it other than assisting at-risk individuals with family planning and reproductive decisions.

 eMedicine - Spherocytosis, Hereditary : Article by Gus Gonzalez, MD
Background: Hereditary spherocytosis (HS) is a familial hemolytic disorder with marked heterogeneity of clinical features, ranging from an asymptomatic condition to fulminant hemolytic anemia.
Given that the incidence of HS in the United States is 1 case in 5000 people and that approximately 25% of all HS is autosomal recessive, calculations indicate that the HS silent carrier state might exist in 1.4% of the population.
HS usually is transmitted as an autosomal dominant trait, and the identification of the disorder in multiple generations of affected families is the rule.

The specific clinical disorder is primary iron overload of adult onset sufficient to cause significant morbidity and mortality.
The original clinical diagnosis of hereditary hemochromatosis was based on the triad of hepatic cirrhosis, diabetes mellitus, and skin pigmentation.
Subsequently, it was shown that the iron deposition in HC is due to excessive absorption of iron from the gastrointestinal tract (Powell et al., 1975; Valberg et al., 1980).

 || DukeMedNews || Genetic Basis of Hereditary Nerve Disorder Revealed
DURHAM, N.C. -- A major form of one of the most prevalent inherited neurological disorders in humans, Charcot-Marie-Tooth disease (CMT), stems from an abnormality in the cellular powerhouses, or mitochondria, that fuel the nerves required for muscle control, suggests new findings by neurogeneticists at the Duke Center for Human Genetics and their international colleagues.
In seven families with a form of the degenerative nerve disorder CMT type 2A, the team discovered that defects in a gene critical to mitochondrial movement, known as mitofusin 2, underlies the disease symptoms.
Restoring the lost gene function through gene therapy might ultimately serve as an effective treatment for the disorder, which currently has no cure, the researchers reported in the April 4, 2004, issue of Nature Genetics.

 Genetic disorder - Wikipedia, the free encyclopedia
Several hereditary diseases are sex-linked, meaning that they afflict one sex much more commonly than the other because the mutation is located on the X (or, rarely, on the Y) chromosome.
X-linked recessive disorders are also caused by mutations in genes on the X chromosome.
The study of genetic diseases is a large scientific discipline, whose theoretical underpinning is based on Population genetics.

 Angioedema, Hereditary
Hereditary angioedema is a rare inherited disorder characterized by recurrent episodes of the accumulation of fluids outside of the blood vessels, blocking the normal flow of blood or lymphatic fluid and causing rapid swelling of tissues in the hands, feet, limbs, face, intestinal tract, or airway.
The most common form of the disorder is hereditary angioedema type I, which is the result of abnormally low levels of certain complex proteins in the blood (C1 esterase inhibitors), known as complements.
Hereditary angioedema type II, a more uncommon form of the disorder, occurs as the result of the production of abnormal complement proteins.

 Links to information on Genetic Hereditary Hemochromatosis
Hereditary hemochromatosis - disorder in which the body stores excess iron which causes damage to organs if untreated.
Hereditary hemochromatosis (HH), also known as iron overload disease, iron storage disease, "genetic iron poisoning", and the "Celtic Curse", is the most common genetic disease in the USA according to the Centers for Disease Control and Prevention (CDC).
Genetic testing can confirm a diagnosis of HFE-associated hereditary hemochromatosis (genetic iron overload) or it can show that the patient is at risk in the future for developing it thereby giving the patient the opportunity to take preventive measures such as diet adjustment and blood donation.

 Evidence of a new hereditary joint disorder   (Site not responding. Last check: 2007-11-04)
While characteristic of osteoarthritis (OA), a degenerative joint disease that affects some 20 million Americans, cartilage erosion and bone abnormalities are also associated with many rare hereditary conditions.
To gain a clearer sense of this syndrome's distinctive signs, the researchers examined blood samples of both the affected family members and unaffected relatives - MM1's parents and 4 siblings - for single nucleotide polymorphisms (SNPs) in the chromosome 2 region which are known to influence bone and cartilage development.

 Nosebleeds May Signal Rare Hereditary Disorder That Attacks Multiple Organs and Leads to Strokes
When epistaxis or nosebleeds occur in multiple members of one family, they are an important clue to a genetic disorder of the blood vessels called Hereditary Hemorrhagic Telangiectasia (HHT) that can lead to strokes and other symptoms, Yale researchers report in two new studies.
