KidsHealth Parents What do you know about your family tree? Have any of your relatives had health problems that tend to run in families? Which of these problems affected your parents or grandparents? Which ones affect you or your brothers or sisters now? Which problems might you pass on to your children? Thanks to advances in genetics, doctors now have the tools to understand how certain illnesses, or increased risks for certain illnesses, pass from generation to generation. According to some health experts, the definition of an inherited or genetic illness should be expanded beyond the classic inherited disorders (like hemophilia and sickle cell anemia ) to include many types of cancer , Alzheimer's disease, and other illnesses. They look toward a future where genetic test results are an important part of every healthy person's medical file. Genes and Chromosomes Each person has a unique set of chemical blueprints that determines how his or her body looks and functions. These blueprints are contained in a complex chemical called deoxy-ribonucleic acid (DNA), a long, spiral-shaped molecule that's found inside each body cell. DNA carries the codes for genetic information and is made of linked subunits called nucleotides. Each nucleotide contains a phosphate molecule, a sugar molecule (deoxyribose), and one of four coding molecules called bases (adenine, guanine, cytosine, or thymine). The sequence of these four bases determines the genetic code.

KidsHealth Parents If you and your partner are newly pregnant, you may be amazed at the number and variety of prenatal tests available to you. Blood tests, urine tests, monthly medical exams, diet questionnaires, and family history forms crowd your schedule and your desk, but each of these tests helps to assess the health of you and your baby - and to predict any potential health risks. Unlike your parents, you may also have the option of genetic testing. These tests identify the likelihood of passing certain genetic diseases or disorders (those caused by a defect in the genes - the tiny, DNA-containing units of heredity that determine the characteristics and functioning of the entire body) to your children. Some of the more familiar genetic disorders are: Down syndrome cystic fibrosis sickle cell anemia Tay-Sachs disease (a fatal disease affecting the central nervous system) If your history suggests that genetic testing would be helpful, you may be referred to a genetic counselor. Or, you might decide to seek out genetic counseling yourself. But what do genetic counselors do, and how can they help your family-to-be?

Kingwood College Library Assignment Guide for Biology 1406 Genetic Disorders Genes are the individual units of DNA, the building blocks of life. When mistakes or mutations occur, they can cause genetic disorders. Hereditary, or germline mutation, can be passed on from generation to generation. Acquired, or somatic mutation, may be caused by environmental stress. Use reference and circulating library books for background information. Journal articles and some information on the web will help you round out your report. TOPICS Choose one of these topics for your research. If you have another genetic disease you would prefer to use, please discuss it with your instructor.

Problem Solving in Genetic Disorders Sau-Ha (Nikki) Chen 1994 Woodrow Wilson Biology Institute Introduction Students often do not see the relevancy of what they learn in school. Knowledge and skills learned in the classroom are not transferred to their everyday life. This activity uses the unit of genetics to cover such concern. Genetics is not only for the scientists, it concerns us all. As knowledge and technology grow more diverse, diagnostic tests and treatment of illnesses are increasingly available in extending the longevity and quality of life. It is important for us to be knowledgeable and to be effective decision makers, and our understanding of both classical and modern genetics gives us the means to do so. All of us can attribute our finer characteristics to genetic lineage. We also may encounter the adverse effects of inheritance in different members of our family, friends and acquaintances. Our basic understanding of genetics answers these questions about our genetic heritage. This activity uses case histories to study genetic disorders and it tests students' knowledge of heredity. These case studies reinforce their understanding of genetic principles. Concepts and skills covered in this activity A. Knowledge

Approximately 5,000 babies with Down syndrome are born each year in the U.S. alone. Down syndrome is a non-hereditary congenital condition usually caused by an extra copy of chromosome 21. Down syndrome is associated with moderate to severe mental retardation, characteristic facial appearance, short stature, hypotonia (low muscle tone), and heart and lung defects. Studies also have indicated that individuals with Down syndrome have a higher incidence of leukemia.

View All Chapters Find Your Local Chapter September 20, 2005 Before You're Pregnant During Your Pregnancy Complications Caring for Your Baby ... [View All Articles] Chromosome Disorders Chromosome Disorders Genetic birth defects can be caused by errors in an entire chromosome or part of a chromosome, rather than in a single gene. These errors occur when the egg or sperm are forming. Occasionally, an extra chromosome is present or a chromosome is missing or broken. This type of problem can come from either the mother or the father. The resulting imbalance of genetic material gives the fertilized egg too little or too much genetic information. When such an error happens, it can be perpetuated each time the cells go through the division process. As the embryo grows, the additional or missing genetic information can translate into a wide range of abnormal body structures and functions, such as heart or kidney conditions and, often, mental retardation. The chances of having a child with a chromosomal inheritance error become greater as women grow older . The possibility of such an error—commonly resulting in Down syndrome —increases throughout the childbearing years. Down syndrome is a pattern of mental retardation and physical abnormalities, often including heart defects.

A person with Down's Syndrome is born with an extra chromosome in each cell in his/her body (i.e. 47 chromosomes instead of the more usual 46). The word 'Syndrome' describes a collection of features or characteristics that tend to be evident in people with the condition (some of these are described below). IS DOWN'S SYNDROME INHERITED? Not usually. Most people who have a baby with Down's Syndrome do not have Down's Syndrome themselves. At some point when the egg or sperm was made, or perhaps at fertilisation, an unusual cell division took place which resulted in an extra copy of chromosome number 21 in all the baby's cells. There is no known reason why this happens. It happens by chance and can happen to anyone, but the chances of it happening increase as the woman gets older. However, a few people are born with Down's Syndrome because they have inherited a chromosome abnormality, called a translation, from one of their parents. A baby born to a mother with Down's Syndrome would also have a high chance of having Down's Syndrome, particularly if the baby's father had Down's Syndrome too.

Glossary of terms Summary The NDSCR has accumulated over 17,000 anonymous records since the Register started in January 1989. It is now probably the largest single dataset on Down syndrome and provides an opportunity to search for possible causal factors. It also enables the study of the response of parents and clinical services to the new technologies of screening and diagnosis. Please see Annual Report (2003) for details. Maternal age is the only well-recognised association of Down syndrome. Mothers below 25 have an average risk of a DS pregnancy of about 1:1600 rising to about 1:340 at 35 and 1:40 at age 43. The data we have suggests that the risk of an affected birth does not increase above this age. Prenatal screening and diagnosis have expanded dramatically in the life of the Register. Despite this expansion, in 1999 44% of all diagnoses were at birth. Prenatal diagnosis depends on an invasive test to obtain fetal cells. Because this entails a risk of fetal loss, of 1 to 2%, it is only offered to mothers with a greater risk of having an affected child. The estimation of this risk, previously limited to high maternal age, is now much more precise with the addition of specific ultrasound and/or maternal serum findings.
