B) Thrombotic organ damage
C) Metastasis of a glioblastoma
D) Amyotrophic lateral sclerosis

Answer 1

Ans: B
Feedback:
Sickle cell anemia is an example of a genetic condition caused by a small gene mutation that affects protein structure, producing hemoglobin S. A person who inherits two copies of the hemoglobin S gene mutation has sickle cell anemia and experiences the symptoms of severe anemia and thrombotic organ damage resulting in hypoxia. Amyotrophic lateral sclerosis is a neurodegenerative disease that can occur as a result of an inherited mutation, but not a mutation of hemoglobin S. The patient with sickle cell anemia may experience edema, but it would not be related to the gene mutation. A glioblastoma is a neurologic tumor.
