Genetic Testing and Disease

See the attached file.

DNA screening
Many corporations have started presenting at home DNA health screening. A person has a cheek swab that isolates DNA and it then evaluated for patterns investigative of disposition to disease, by of which a lot of these disorders are still yet to be curable.

-What are a few disadvantages/advantages of tests for breast cancer, of which there is surgical intervention and non-genetic screening, but little behavioral modifications that affect progression?

-What are some disadvantages/advantages of such a test for a 4-fold decreased risk of heart disease (for which there is nonsurgical/surgical intervention and progression of which behavioral modification)?

-A 2-fold increased risk of Lou Gehrig's disease (for which there is little screening, little effect of behavioral modification, and no known effective intervention?

-In each case the gene in question indicates an altered risk, but not a guarantee that the individual either will or will not contract the disease.

Research in the field of breast cancer has led to the identification of genes commonly mutated in breast cancer patients, namely BRCA1 and BRCA2. Genetic tests are currently available to identify the most common mutations in these breast cancer genes that may predispose a patient to developing breast cancer. Remember these tests indicate a predisposition but do not guarantee the ...
