Problem 15
Textbook Question
Textbook QuestionThe family of a sixth-grade boy in Palo Alto, California, was informed by school administrators that he would have to transfer out of his middle school because they believed his mutation of the CFTR gene, which does not produce any symptoms associated with cystic fibrosis, posed a risk to other students at the school who have cystic fibrosis. After missing 11 days of school, a settlement was reached to have the boy return to school. What ethical problems might you associate with this example?

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
CFTR Gene and Cystic Fibrosis
The CFTR gene encodes a protein that regulates the movement of salt and water in and out of cells. Mutations in this gene can lead to cystic fibrosis, a serious genetic disorder that affects the lungs and digestive system. Understanding the nature of the specific mutation in the boy's case is crucial, as some mutations may not lead to symptoms, raising questions about the implications of labeling individuals based on genetic information.

Genetic Discrimination
Genetic discrimination occurs when individuals are treated unfairly based on their genetic information. In this scenario, the boy's transfer from school due to his CFTR mutation raises ethical concerns about whether it is justifiable to exclude someone based on potential risks associated with their genetic makeup, especially when they exhibit no symptoms of the condition.

Ethical Considerations in Education
Ethical considerations in education involve balancing the rights and needs of individual students with the safety and well-being of the larger school community. This case highlights the tension between protecting students with cystic fibrosis and ensuring that all students, including those with genetic mutations, have equal access to education, prompting discussions about inclusivity and the role of schools in addressing health-related concerns.
