Since males do not have an additional copy of X to offset a defect, most X- linked diseases affect males. This is likely due to X inactivation, a normal process whereby one X chromosome is randomly inactivated in every cell. The endocrine glands consist of: pineal; pituitary; thyroid and parathyroids; thymus; adrenals; pancreas; ovaries (female); and testes (male). Hormones are the chemical signaling molecules produced by the endocrine glands and secreted directly into the bloodstream. They travel through the blood to distant tissues and organs, where they can bind to specific cell sites called receptors. By binding to receptors, hormones trigger various responses in the tissues containing the receptors. Myocytes in the atria of the heart and scattered epithelial cells in the stomach and small intestine are examples of what is sometimes called the "diffuse" endocrine system. If the term hormone is defined broadly to include all secreted chemical messengers, then virtually all cells can be considered part of the endocrine system. Advances in molecular genetics have led to a greatly strengthened understanding of the mechanisms of certain of the hereditary endocrine disorders. This section of genes and disease focuses on disorders for which the primary gene defect has been characterized or recently identified. There are two copies of the gene because of a duplication that occurred hundreds of thousands of years ago. The 21- hydroxylase deficiency is unique because most mutations result from the transfer of genetic informa- tion between inactive and active genes. In the absence of 21-hydroxylase, affected indi- viduals are unable to make cortisol and aldosterone. But because of the missing enzyme, cortisol and aldosterone levels still do not rise. Aldosterone deficiency can cause a "salt wasting crisis" where the body loses too much salt and, eventually, water. The This may result in girls being born with masculine- production of several important hormones is appearing external genitals. A mouse deficient in 21-hydroxylase is proving to be a Corticosteroids, such as cortisol, are important in the bodys response to illness or injury. It is still a mystery as to how the transporter affects the function the fatty acid enzyme and, for that matter, how high levels of very long chain fatty acids cause the loss of myelin on nerve fibers.

Sulfate is important for skeletal joints because cartilagethe shock-absorber of jointsrequires sulfur during its manufacture. Adding sulfur increases the negative charge within cartilage, which contributes to its shock-absorbing properties. A great deal of further research must be done before this condition is fully understood and effective therapies are developed. Arteries are the passageways through which the blood is delivered, the largest of which is the aorta. The aorta branches off the heart and divides into many smaller arteries, which have muscular walls that adjust their diameter to increase or decrease blood flow to a particular body area. Capillaries are thin walled, highly branched vessels that feed the tissues and collect wastes to be carried back to the lungs, liver, or kidney for elimination. Capillaries empty into the venules, which in turn drain into the veins that lead back to the heart. Veins carry deoxygenated blood to the lungs to pick up more oxygen, and then back to the heart once again. The four most common types of vascular disease are high blood pressure, coronary heart disease, stroke, and rheumatic heart disease. Some of these disorders are the result of the over production of blood vessel cells, while others occur from vascular malformations. Still others result from inflammation of the blood vessels or the build up of a fatty substance called plaque within the blood vessels. It is charac- great deal of research is still required before we can terized by a narrowing of the arteries caused by fully understand the mechanisms that regulate the cholesterol-rich plaques of immune system cells. A protein called apolipoprotein E, which can exist in several different forms, is coded for by a gene found on chromosome 19. It is important for removing excess cholesterol from the blood, and does so by carrying cholesterol to receptors on the surface of liver cells. Currently, a debate is raging over how the vari- ous mutated forms of apolipoprotein E effect the body.

Beta blockers are used to treat the symptoms of the disease, and appear to be effective in some symptomatic patients.

In normal cells, elastin is a key component of connective tissue, conferring its elastic properties. Mutation or deletion of elastin lead to the vascular disease observed in Williams syndrome. Williams syndrome is a contiguous disease, meaning that the deletion of this section of chromo- some 7 may involve several more genes. If a person is born with a severely defective immune system, death from infection by a virus, bacterium, fungus or parasite will occur. In severe combined immunodeficiency, lack of an enzyme means that toxic waste builds up inside immune system cells, killing them and thus devastating the immune system. A lack of immune system cells is also the basis for DiGeorge syndrome: improper development of the thymus gland means that T cell production is diminished.
