Question

A deficiency of ________________ results in Friedreich's ataxia, a disease that affects the nervous, heart and skeletal system.

Answer 1

Friedreich's ataxia, a disease that affects the nervous, heart and skeletal systems, is caused by a deficiency of frataxin, a protein involved in iron metabolism.

Step-by-step explanation:

Friedreich's ataxia is a disease that affects the nervous, heart, and skeletal systems. It is caused by a deficiency of frataxin, a protein involved in iron metabolism. The lack of frataxin leads to an accumulation of iron in certain cells, which ultimately results in the degeneration of nerve cells in the spinal cord and other parts of the body. This degeneration leads to the various symptoms of Friedreich's ataxia, including difficulty with coordination and movement.
