Quizplus · Accepted Answer

Multiple sclerosis is believed to be caused by a combination of genetic and environmental factors. While there is a genetic component, it is not a simple case of strong heritability. Environmental factors such as infections, smoking, and vitamin D deficiency have been linked to an increased risk of developing multiple sclerosis. Excessive sun exposure is not considered a significant risk factor for multiple sclerosis.
