Identifiy the autoimmune disease among the following.

Options

A. Myasthenia gravis
B. Albinism
C. Muscular dystrophy
D. Endemic goitre

Answer

To identify the autoimmune disease among the given options, we can follow these steps:

### Step 1: Understand Autoimmune Diseases
Autoimmune diseases occur when the immune system mistakenly attacks the body's own healthy cells, tissues, or organs. It's essential to recognize the characteristics of autoimmune diseases to differentiate them from other conditions.

**Hint:** Look for conditions where the immune system is involved in attacking the body’s own cells.

### Step 2: Analyze Each Option
1. **Myasthenia Gravis**: This is a chronic autoimmune disorder where antibodies destroy the communication between nerves and muscles, leading to weakness in voluntary muscles, especially those controlling the eyes, mouth, throat, and limbs.

**Hint:** Focus on conditions that involve immune system dysfunction affecting muscle or nerve communication.

2. **Albinism**: This condition is caused by mutations in genes that produce melanin. It is not related to the immune system attacking the body.

**Hint:** Consider whether the condition is linked to genetic mutations rather than immune responses.

3. **Muscular Dystrophy**: This is a group of diseases caused by genetic mutations that lead to progressive weakness and loss of muscle mass. It does not involve the immune system.

**Hint:** Look for conditions that are primarily genetic and not autoimmune.

4. **Endemic Goiter**: This is caused by iodine deficiency, leading to thyroid gland enlargement. It is not an autoimmune condition.

**Hint:** Identify if the condition is related to nutritional deficiencies rather than immune system issues.

### Step 3: Identify the Correct Answer
From the analysis:
- Myasthenia Gravis is the only condition that fits the definition of an autoimmune disease, as it involves the immune system attacking the communication between nerves and muscles.

**Final Answer:** Myasthenia Gravis is the autoimmune disease among the options provided.

### Summary
The autoimmune disease among the options is **Myasthenia Gravis**. The other conditions listed are either genetic disorders or related to nutritional deficiencies, not autoimmune in nature.
