In March 2001, the nationwide Institutes of well-being issued the next caution: "The variety of websites providing health-related assets grows each day. Many websites offer necessary details, whereas others could have details that's unreliable or misleading." in addition, as a result quick bring up in Internet-based details, many hours might be wasted looking out, identifying, and printing. considering that merely the smallest fraction of knowledge facing 47,XYY syndrome is listed in se's, resembling or others, a non-systematic method of web examine should be not just time eating, but in addition incomplete. This booklet was once created for doctors, scholars, and contributors of most people who are looking to behavior scientific study utilizing the main complicated instruments on hand and spending the smallest amount of time doing so.

Example text

The chromosome arm is the second part of the gene’s address. For example, 5q is the long arm of chromosome 5, and Xp is the short arm of the X chromosome. • The position of the gene on the p or q arm. The position of a gene is based on a distinctive pattern of light and dark bands that appear when the chromosome is stained in a certain way. The position is usually designated by two digits (representing a region and a band), which are sometimes followed by a decimal point and one or more additional digits (representing sub-bands within a light or dark area).

Factors that Influence the Effects of Particular Genetic Changes Reduced penetrance and variable expressivity are factors that influence the effects of particular genetic changes. These factors usually affect disorders that have an autosomal dominant pattern of inheritance, although they are occasionally seen in disorders with an autosomal recessive inheritance pattern. Reduced Penetrance Penetrance refers to the proportion of people with a particular genetic change (such as a mutation in a specific gene) who exhibit signs and symptoms of a genetic disorder.

The effects of these conditions are most pronounced in organs and tissues that require a lot of energy (such as the heart, brain, and muscles). Although the health consequences of inherited mitochondrial DNA mutations vary widely, frequently observed features include muscle weakness and wasting, problems with movement, diabetes, kidney failure, heart disease, loss of intellectual functions (dementia), hearing loss, and abnormalities involving the eyes and vision. Mitochondrial DNA is also prone to noninherited (somatic) mutations.
