Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The ApoE gene encodes apolipoprotein E, which plays a crucial role in lipid metabolism. A single base polymorphism in the ApoE gene, particularly the ApoE4 allele, is strongly associated with an increased risk of Alzheimer’s disease.
- Option D: Correct. ApoE4 allele increases susceptibility to Alzheimer’s disease.
- Option A, B, C: Incorrect. These conditions are linked to other genes or factors, not the ApoE gene.
