For This Assignment You Will Think About Your Individual Health And He

For this Assignment you will think about your individual health and health risks. What genetic diseases or problems might you face during your lifetime? Predisposition to heart disease, breast cancer, diabetes? You may consider your own health risks or those of other individuals such as a family member or friend. Then, in a paper of 750–1,000 words, address the following issues: What genetic diseases or problems were determined to be potential issues?

Provide an introduction of the disease, outlining the major signs/symptoms of the disorder and the reason why this was selected as a genetic/inherited disease. Research the mode of inheritance for this disease/trait. Why? If you are not able to find a specific mode of inheritance, provide a hypothesis for the mode of inheritance. Explain your thinking very thoroughly; this should take up about half of the length of the Assignment.

What other information would help you draw better conclusions about this disease? What problems did you encounter in gathering information about your family's history or that of the person you interviewed? If you were to have a child, what could you tell him or her about his/her chances of inheriting the diseases based upon your research about the inheritability of the trait you are researching? Finally, visit the KU library by clicking on the “Library” link on the KU Campus homepage. Select the option to perform an advanced search.

Find two references that pertain to the disease/trait you selected. Record the methods that you used to discover these sources, and answer the following questions: Which search term(s) did you use? Did you use combinations of search terms? Which methods resulted in the most “hits” or results? Did you refine any of your searches? Also, briefly explain whether the references support or contradict your previous conclusions.

Paper For Above instruction

The assessment of individual health risks rooted in genetic predispositions provides a vital understanding of potential health challenges throughout a person's life. For this paper, I focus on hereditary breast cancer, a significant concern for many individuals with familial history. Breast cancer remains one of the most common cancers affecting women worldwide, with genetic factors playing a pivotal role in its development. The primary gene associated with hereditary breast cancer is BRCA1, and mutations in this gene substantially increase an individual’s risk of developing breast and ovarian cancers. This exploration delves into the characteristics of this disease, its mode of inheritance, challenges in gathering family health history, and the relevance for prospective children, supported by scholarly research obtained through the KU library.

Introduction to Hereditary Breast Cancer

Hereditary breast cancer is a form of breast cancer caused by inherited genetic mutations. Unlike sporadic breast cancers, which develop due to environmental factors and somatic mutations, hereditary cases are linked to germline mutations passed from parent to offspring. The dominant signs include a strong family history of breast or ovarian cancer, early onset of disease, and bilateral breast cancer occurrences. Symptoms of breast cancer typically include lumps, nipple changes, and skin alterations, but in hereditary cases, early detection and genetic screening are crucial for risk management.

The reason for selecting hereditary breast cancer as a focus stems from its clear genetic basis and significant implications for individuals with family histories. The identification of BRCA1 and BRCA2 mutations has revolutionized risk assessment, preventive strategies, and treatment options, emphasizing the importance of understanding inherited cancer syndromes.

Mode of Inheritance and Genetic Mechanisms

Hereditary breast cancer primarily follows an autosomal dominant inheritance pattern. Mutations in BRCA1 and BRCA2 are inherited in a dominant manner, where a single copy of the mutated gene significantly elevates cancer risk. Both males and females can carry these mutations, but the phenotypic expression is more evident in women. Each child of a carrier has a 50% chance of inheriting the mutation.

If specific inheritance patterns were elusive, a hypothesis could be that the trait operates as a multifactorial inheritance involving both genetic susceptibilities and environmental factors. However, existing evidence robustly supports the autosomal dominant model due to family linkage studies and pedigree analyses.

Understanding the inheritance mode assists in genetic counseling and risk prediction, enabling targeted screening and preventive measures for at-risk individuals.

Additional Information for Better Conclusions

Gathering comprehensive family history, including detailed records of cancers in relatives and age of onset, enhances the accuracy of risk assessment. Molecular genetic testing for BRCA1 and BRCA2 mutations provides definitive evidence of inherited risk. Challenges encountered include incomplete family medical records, reluctance of relatives to participate in genetic testing, and variability in the penetrance of mutations.

Better insights could also be obtained through population-specific studies, environmental exposure data, and longitudinal health monitoring. These factors would refine risk models and improve predictive precision.

If I were to have a child, I could inform them about the inherited nature of the disease, emphasizing the importance of genetic testing and early screening. I would explain that, depending on my genetic makeup, their chances of inheriting the mutation could be 50%, influencing their lifetime risk of developing breast cancer.

Research Methods and Source Selection

Utilizing the KU library's advanced search, I started with search terms like "hereditary breast cancer," "BRCA1 mutations," and "genetics of breast cancer." I combined terms such as "BRCA1 AND inheritance" to narrow results. Initial searches yielded broad results, which I refined by applying filters for peer-reviewed articles, recent publications, and research journals, resulting in more targeted and relevant sources.

The two scholarly references selected include a review article on BRCA1 and BRCA2 functions and a detailed epidemiological study on hereditary breast cancer prevalence. The methods used involved combining keywords related to genetic mutations and familial cancer patterns, which yielded high-quality results. These references support the understanding that hereditary breast cancer is primarily inherited through autosomal dominant mutations, which aligns with my prior conclusions, but they also highlight areas for further research, such as gene-environment interactions.

Conclusion

Assessing inherited genetic risks, particularly through hereditary breast cancer, underscores the importance of accurate family history collection, genetic testing, and informed counseling. Knowledge of the inheritance pattern helps predict individual risks and guides preventive strategies. Despite challenges in data collection, advancements in genetic research and database searches foster better understanding and management of inherited diseases, ultimately aiding in personalized medicine and family health planning.
