A patient tells the nurse that many of her family members have a type of anemia that is genetic. The nurse realizes that this patient will:
1. Develop the disease only if there is a mutation in the gene.
2. Develop the same type of anemia.
3. Die from the anemia.
4. Develop the disease only if the gene translocates.
Develop the disease only if there is a mutation in the gene.
Rationale: All humans have essentially the same 20,000 to 25,000 genes; it is the mutation or polymorphism in the gene, not translocation nor the gene itself, that predisposes some individuals for disease. The patient may or may not develop or die from anemia.
