Previous Section This Issue- Table of Contents Next Section Molecular Genetic Testing in Mainstream Medicine Vol. 14: Spring, 1997 DNA Testing for Hereditary Hemochromatosis Introduction Key Points The HH gene and mutations Indications for DNA testing ... Illustrative case report Introduction Hereditary hemochromatosis (HH) is regarded as the most common genetic disorder in Caucasians, with an estimated prevalence of 1/200-1/400 (homozygotes) and a carrier frequency (heterozygotes) of 1/8-1/10. It is an excellent example of a common genetic disorder with high morbidity and mortality which is preventable if diagnosed early. A DNA test for hemochromatosis has recently become available and will be a valuable aid for early detection of this disorder. Hemochromatosis is characterized by increased iron absorption in the intestine, resulting in a gradual build-up of excess iron (iron overload). Most homozygotes develop symptoms in adulthood, although the age of onset has been as young as 2 years. Heterozygotes are usually asymptomatic. Early symptoms in homozygotes are multisystemic and often non-specific, including malaise, fatigue, impotence, abdominal pain, or joint pain. As iron storage increases, deposits occur in organs such as the liver, heart, and pancreas, leading to organ damage and dysfunction.

Illustrative Case Report Introduction The Prader-Willi and Angelman syndromes are distinct mental retardation disorders, but frequently discussed together because both are due to genetic abnormalities of chromosome 15. Genetic testing for these disorders has improved markedly over the last 15 years, reflecting our understanding of the molecular basis of these two conditions. This review will summarize the clinical findings, history of genetic testing and understanding of the basis of these conditions, and current recommendations for testing with a case example. Both syndromes can be diagnosed by history and physical examination, but the laboratory tests are helpful for clinical confirmation, in very young patients where a phenotype has not evolved, in prenatal diagnosis, and in defining recurrence risks.

DNA Testing resources on DNA testing. Why do paternity testing? How do DNA tests usually work? Purposes of various kinds of testing Test Purpose/Samples Needed From ... Resources Why do paternity testing? Parental and Foresnsic Testing To establish an accurate medical history for the child. To prevent disputes in adoption To create a record for immigration To foster peace of mind for all involved parties To obtain child support. To determine the birth father. To determine the birth mother (cases of switching babies in the hospital shortly after birth.) How do DNA tests usually work? The test is based upon the principals of inheritance. A child gets one half of his/her genetic makeup from the mother and the other half from the biological father. The test reveals a control batch of genetic markers from all parties. The genetic markers that the child shares with the mother are first located. Then to determine paternity, the child's remaining markers are compared to the alleged father. If the man is indeed the father, all of the markers that did not match the mother's should match his. If all of the child's remaining markers match the alleged father, evidence is provided that he is the biological father of the child. If they do not match, he is excluded as the biological father of the child. When the mother is not tested, a larger batch of control markers are revealed from the alleged father and child. If these markers show tat the man is contributing half of the genetic makeup of the child, he is given evidence that he is the biological father of the child. If markers are found not to match between the alleged father and child, the man is excluded from being the biological father of the child.

Other techniques are used to detect tiny changes in the DNA code. These usually involve extracting the DNA from a blood sample of the person being tested and making many copies of it (link to PCR). The DNA is then cut into small fragments using restriction enzymes and the samples are compared with other samples from people with and without a particular mutation. cystic fibrosis , some forms of haemophilia and muscular dystrophy Huntington's disease thalassaemia and Tay-Sachs disease Looking at chromosomes Some genetic disorders can be detected by examining a person's cells, using high-powered microscopes to look for changes in chromosome number and structure. When cells divide, chromosomes reproduce themselves and then coil up into compact shapes to make their division easier. In this state the chromosomes can be stained, photographed and arranged for easy identification and comparison. These photographs are called karyotypes . 'Probing' the chromosomes with fluorescent stains allows particular chromosomes to be picked out and abnormalities to be identified. An extra copy of the genetic material of chromosome 21 is responsible for

DNA DIAGNOSTIC TESTING FOR ALPORT SYNDROME DIRECT TEST FOR MUTATIONS IN THE COL4A5 GENE AND GENETIC LINKAGE TESTING DNA.htm Version of August 31, 1999 NOTE by Webmaster Curtis L. Atkin : The original version of this article appeared in the HNF Newsletter No. 24, March 1992 . I have here updated some addresses. Prospective clients should see the newer page DNA Diagnostic Lab Alport Syndrome , and also might well read both Should You Consider Gene Testing? and Understanding Gene Testing The University of Utah DNA Diagnostic Laboratory is now offering diagnostic testing for the hereditary kidney disease of Alport syndrome. This testing has recently become possible because of research at University of Utah, University of Oulu (Finland), and elsewhere to discover the abnormal genes which cause this disease. Testing is relatively expensive but is covered by many forms of health insurance. DNA tests can be used to diagnose "at risk" children that may show few or no signs or symptoms of Alport syndrome. Gene-carrier status may also be determined in asymptomatic adult females at risk, as well as in potential kidney donors within a family. DNA testing can even be performed before birth. For about 15% of families with Alport syndrome, a straightforward test called "Southern blotting" offers direct demonstration of abnormalities, or mutations, in the COL4A5 "Alport" gene on the X chromosome. This test requires blood samples from one or more persons.

Drug Reaction Testing Do not alter the dosage amount or schedule of any drug you are taking without first consulting your doctor or pharmacists. Research shows that of all the clinical factors such as age, sex, weight, general health and liver function that alter a patient's response to drugs, genetic factors are the most important. This information becomes even more crucial when you consider the fact that adverse reactions to prescription drugs are killing about 106,000 Americans each year roughly three times as many as are killed by automobiles. This makes prescription drugs the fourth leading killer in the U.S., after heart disease, cancer, and stroke. We currently offer CYP2D6, CYP2C9, and CYP2C19 screens that can help your physician or druggist predict your particular response to more than a quarter of all prescription drugs.
