	Genetic Disorders - MSN Encarta
		Genetic changes that are not inherited (somatic mutations) may cause or contribute to such disorders as cancer.
		A special type of single gene disorder occurs when the mutation lies in one of the genes found in the mitochondria of the cell; these are small bodies which carry their own genetic material within a cell.
		Genetic disorders transmitted through the mitochondria thus affect all the children of an affected woman but none of the children of an affected man. An example of this is Leber's hereditary optic neuropathy, a disorder characterized by atrophy of the optic nerve.

		Genetics is the study of how traits — such as blood type — are passed from parent to child through genes and chromosomes.
		Genetic disorders may be caused by problems with either genes or chromosomes.
		Disorders that are caused by genes on the X chromosome are called X-linked or sex-linked disorders.

	Genetic Testing
		But other genetic tests measure your risk of developing a disease, even if you are healthy now (presymptomatic testing), or whether you and your partner are at risk of having a child with a genetic disorder (carrier screening).
		If a genetic disorder for which a test is available has surfaced on either side of the family, or if you and your partner are carriers for the same testable recessive disorder, your health care professional will probably suggest testing, to determine if the fetus has inherited the disease.
		This autosomal recessive disorder is diagnosed in childhood.

	Genetic Disorders: The Links to Diet
		Many researchers and support groups state that birth defects and genetic disorders, especially connective tissue disorders such as Marfan syndrome, osteogenesis imperfecta and Ehlers-Danlos syndrome, can't possibly be cured through diet because they are inherited genetic disorders.
		At one time many genetic researchers were convinced that spina bifida was entirely a genetic disorder, yet we now know that almost all cases of spina bifida have been shown to be preventable if the mother gets adequate folic acid before and during her pregnancy.
		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.

	Genetic Disorders Information on Healthline
		However, if both parents lack the disorder and pass the disorder's gene to a child, then the genetic disorder is said to be recessive.
		Disorders that result from both genes and environment are called multi-factorial genetic diseases.
		In addition, some genetic disorders occur predominantly in males or females, due to the nature of the sex chromosomes, X and Y. Although many genetic diseases, such as cystic fibrosis and sickle-cell anemia, do not occur often, some more common genetic diseases include hypertension, diabetes, and certain forms of cancer.

	Genetic counseling (Site not responding. Last check: 2007-10-03)
		A genetic counselor, with the aid of the patient or family, creates a detailed family pedigree that includes the incidence of disease in first-degree (parents, siblings, and children) and second-degree (aunts, uncles, and grandparents) relatives.
		Genetic disorders such as Tay-Sachs disease, sickle-cell anemia, and thalassemia meet these criteria, and screening tests are commonly done to identify carriers of these diseases.
		Genetic diagnosis requires that a couple share information about inherited disorders in their background with the genetic counselor, including details of any genetic diseases in either family.

		Genetic tests also determine whether or not couples are at a higher risk than the general population for having a child affected with a genetic disorder.
		Genetic disease results from a change, or mutation, in a chromosome or in one or several base pairs on a gene.
		Some genetic diseases occur as a result of a larger mutation which can occur when the chromosome itself is either rearranged or altered or when a baby is born with more than the expected number of chromosomes.

	Genetic disorder - Wikipedia, the free encyclopedia
		Cystic fibrosis is one of the most common genetic disorders; around 5% of the population of the United States carry at least one copy of the defective gene.
		Where genetic disorders are the result of a single mutated gene they can be passed on to subsequent generations in the ways outlined in the table below.
		For example, achondroplasia is typically considered a dominant disorder, but young goats or children with two genes for achondroplasia have a severe skeletal disorder that achondroplasics could be viewed as carriers of.

	Frequently Asked Questions: Cardiovascular Genetics Center
		Genetic testing examines a DNA sample – taken from a sample of blood or any body tissue – to test for changes in the genes, called mutations.
		Researchers at the Cardiovascular Genetics Center are at the forefront of new discoveries about the molecular mechanisms that underlie genetic cardiovascular disorders – providing clinicians and patients with valuable information that may not be available elsewhere and suggesting new options for treatment.
		If a genetic test is available and confirms that you did not inherit the mutation causing the cardiovascular disease in your family, you do not need further evaluation or treatment for this condition and you are not at risk to pass this condition on to your children.

	Genetic Screening: Genetic Disorders Detection: Merck Manual Home Edition
		Genetic screening is used to determine whether a couple is at increased risk of having a baby with a hereditary genetic disorder.
		Genetic screening involves assessing the couple's family history and may involve determining whether a prospective parent who does not have symptoms of a particular disorder has a gene for that disorder (carrier screening).
		To determine whether having a baby with a genetic disorder is likely, doctors ask the couple about disorders that family members have had and about the cause of death in family members.
