All of the following are true statements about Cockayne syndrome, EXCEPT
**Core Concept**
Cockayne syndrome is a rare, autosomal recessive disorder characterized by premature aging, growth failure, impaired development, and sensitivity to ultraviolet (UV) radiation. It is caused by mutations in the ERCC6 or ERCC8 genes, which are involved in nucleotide excision repair (NER) of DNA damage.
**Why the Correct Answer is Right**
Cockayne syndrome is indeed characterized by growth failure, impaired development, and sensitivity to UV radiation. The ERCC6 and ERCC8 genes play crucial roles in the NER pathway, which is essential for repairing DNA damage caused by UV radiation and other mutagenic agents. Mutations in these genes lead to impaired DNA repair, resulting in the characteristic features of Cockayne syndrome.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided, so we'll start with the next one.
* **Option B:** This option is not provided.
* **Option C:** This option is not provided.
* **Option D:** This option is not provided.
Since the correct answer is not provided, we'll assume that the options are placeholders for actual statements about Cockayne syndrome. Let's assume that one of the options is incorrect based on the characteristics of the disease.
**Clinical Pearl / High-Yield Fact**
Cockayne syndrome is often associated with progressive neurological deterioration, including hearing loss, vision loss, and intellectual disability. Patients with Cockayne syndrome are also at increased risk of developing skin cancers due to their impaired DNA repair mechanisms.
