Question

What is true about the national history and epidemiology of \(\mathbf{H D}\) ? a. Men are affected more than woman. b. It is an inherited genetic disorder where an accurate test is not available. c. Description of the disease complex was ascribed to Frederick Huntington in \(1972 .\) d. All of the above. e. None of the above

Short answer

Answer: None of the above.

Step-by-step solution

Evaluate option (a)

According to various scientific research and data available on Huntington's Disease, this disease affects men and women equally. It doesn't discriminate based on gender. Therefore, option (a) is not true.

Evaluate option (b)

Huntington's Disease is indeed an inherited genetic disorder that is caused by a mutation in the individual's HTT gene. However, there is an accurate genetic test available today to diagnose this disease. A person can undergo genetic testing to find out if they carry the mutated gene responsible for causing HD. Therefore, option (b) is not true either.

Evaluate option (c)

The description of the disease complex was ascribed to George Huntington, not Frederick Huntington. Furthermore, George Huntington published his paper on the disease in 1872, not 1972 as mentioned in the statement. Therefore, option (c) is not true.

Evaluate option (d) and (e)

Since none of the individual statements (a), (b), and (c) are true, option (d) "All of the above" cannot be the correct answer. The only remaining option is (e) "None of the above," which is the correct answer for this exercise. The correct answer is: (e) None of the above.
