All of the following are X-linked disorders except –
**Core Concept**
X-linked disorders are genetic conditions caused by mutations in genes located on the X chromosome. They predominantly affect males, who have only one X chromosome, as a single mutated gene can cause the condition. Females, who have two X chromosomes, are less frequently affected but can be carriers of the mutated gene.
**Why the Correct Answer is Right**
To answer this question, we need to identify X-linked disorders among the options. X-linked disorders are characterized by their inheritance pattern and clinical presentation. A classic example of an X-linked disorder is **Hemophilia A**, caused by a deficiency of factor VIII. Another example is **Duchenne muscular dystrophy**, caused by a mutation in the dystrophin gene.
**Why Each Wrong Option is Incorrect**
**Option A:** **Option B:** **Option C:**
* **Option A:** Not a valid option
* **Option B:** Not a valid option
* **Option C:** Not a valid option
**Clinical Pearl / High-Yield Fact**
Be aware that X-linked disorders can be inherited in an X-linked recessive pattern, where affected males pass the mutated gene to all their daughters, who become carriers. Carriers have a 50% chance of passing the mutated gene to each son, who will be affected, and a 50% chance of passing the normal gene to each daughter, who will not be affected.
