Sickle cell anemia a case study approach to teaching high school genetics

These red blood cells are destroyed at an increased rate, causing anemia. Have students do this "An Inventory of My Traits" activity. Catalog, Dayton, Indiana, It can be manufactured for therapeutic use with recombinant DNA technology. Black men who were diagnosed with HIV generally fared worse than their white and Hispanic counterparts.


In contrast to Turner syndrome, which results from the absence of a sex chromosome, three alternative conditions result from the presence of an extra sex chromosome: These linkages should be more closely evaluated than by ethnicity.

Research fields include hemoglobinopathies, disorders of iron metabolism, non invasive methods for body iron assessment, and development of drugs as iron chelators, and modulators of bone marrow activity.

The abstract and poster presentations will take place during the three days. By walking through this short and graphic activity, students will develop a better understanding of what exactly the RFLP diagnostic test entails and how gels and southern blots work in practice.

Solid symbols represent affected individuals, and open symbols represent unaffected individuals. Nature Medicine 6, My role includes providing management, professional and clinical leadership to a team of skilled specialist haemoglobinopathy nurses, in the delivery of high-quality integrated community based, nursing service.

Although the biochemical basis of numerical chromosome abnormalities remains unknown, maternal age clearly has an effect, such that older women are at significantly increased risk to conceive and give birth to a chromosomally abnormal child.

Connect the electrodes to the gel box and to the power supply red to red, black to black.

Individuals with the AS genotype do not develop sickle cell anemia and have less chance of contracting malaria. The human genome is encoded in DNA [39] For any trait of interest, observed differences among individuals "may be due to differences in the genes" coding for a trait or "the result of variation in environmental condition".

As a result, an affected heterozygote has a 50 percent chance of passing on the disease gene to each of his or her children.

Mainly training in the field of not oncologic hematology to include in particular congenital blood disorders, the iron metabolism alterations, the overall approach to chronic diseases with high clinical complexity, rare diseases both adult and pediatric.

Nonetheless, a small increased risk is generally cited for these couples to account for unusual situations, such as chromosomal translocations or gonadal mosaicism, described below.

In order to tackle this issue, a multi-disciplinary sub-group of the Sickle Cell and Thalassaemia Advisory Group set about looking at the whole system to determine why women are tested late.

Notifying the child about what activities they can or cannot do, what to do when they feel chest pains, and basic information on how to handle the effects of the disease can help prevent any future harm that comes from SCA.

These children have the mutated gene, but they do not usually show symptoms of the disease Fig. Napthol blue black NB mimics the smaller-fragment band bp, representing the A allele.

The homozygote for a dominantly inherited abnormal gene may be equally affected with the heterozygote. Heterozygous individuals are usually healthy, but they may suffer some symptoms of sickle cell anemia under conditions of low blood oxygen, such as high elevation.Genetics Education Partnership has an entire "Sickle Cell Anemia: A Case Study Approach to Teaching High School Genetics" unit that includes worksheets and labs.

The two videos in the unit, "Blood is Life" and "Children By Design," can be ordered from the Films Media Group. Human genetic disease, any of the diseases and disorders that are caused by mutations in one or more genes. With the increasing ability to control infectious and nutritional diseases in developed countries, there has come the realization that genetic diseases are a major cause of disability, death, and human tragedy.

The desire to eradicate disease is the desire to help others; it is a moral impulse derived from our best social instincts. The expression of this desire through advanced science provides us with new methods of preventing disease.

Summary: Sickle cell anemia is an example of a genetic disease that can serve as a vehicle for teaching many biology concepts. Using a case study approach, opportunities arise to make connections not only to various aspects of genetics and molecular biology, but to physiology.

Texas Oncology is a group more than physicians focused on treating cancer and blood disorders. Search our network by physician, location or specialty. The management of newly diagnosed and relapsed acute lymphocytic leukemia (ALL) has traditionally relied on combination chemotherapy, but novel immune-based approaches are rapidly changing the treatment landscape.
