Question

Mutations in mitochondrial genes play a role in each of the following diseases except: A) adult onset diabetes. B) cystic fibrosis. C) hypertrophic cardiomyopathy. D) Leberâs hereditary optic neuropathy. E) myoclonic epilepsy.

Answer 1

Hi! The correct answer to this question would be B. Cystic fibrosis is caused by a mutation with the CFTR gene, leading to infection of the lung and even other organs in the body. One of the main things mitochondria does for the lungs in mucus secretion, but without the CFTR gene, it creates a thickening of the mucus. Hope this helps :).
