**Core Concept**
Epidermolysis bullosa (EB) is a group of genetic disorders characterized by skin fragility and blisters. The condition arises due to mutations in genes involved in the anchoring of the epidermis to the dermis, leading to impaired skin integrity.

**Why the Correct Answer is Right**
The correct answer is related to the molecular basis of EB. The disease is caused by mutations in genes that encode for proteins crucial for skin adhesion, such as collagen VII (COL7A1), laminin 332, and others. These proteins form a complex network that anchors the epidermis to the dermis. Mutations in these genes lead to the production of abnormal proteins or a complete absence of the protein, resulting in skin fragility and blistering.

**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect because it does not specify the molecular basis of EB.
* **Option B:** Incorrect because it is a nonspecific term and does not relate to the genetic cause of EB.
* **Option C:** Incorrect because it is a misnomer; EB is not caused by an autoimmune response, but rather by genetic mutations.

**Clinical Pearl / High-Yield Fact**
Epidermolysis bullosa is a rare genetic disorder that affects skin integrity and can be caused by mutations in multiple genes involved in skin adhesion.

**Correct Answer:** D.
