Multiple sclerosis is affected by non-genetic factors including place of birth. Risk of MS associated with birth place

Question

Quizplus · Accepted Answer

Studies have shown that risk of multiple sclerosis is influenced by place of birth, with higher risk in certain geographical areas. However, if an individual moves to a new area at an early age (before age 15), their risk of developing MS may be closer to that of their new location rather than their birthplace. This suggests that environmental factors in the new location may play a greater role in the development of MS than genetic factors inherited from one's birthplace. Therefore, option C is the correct answer. Option A is incorrect because the risk does change after relocation. Option B is incorrect because the timing of relocation, particularly before or after adolescence, is an important factor. Option D is incorrect because there is no evidence to suggest that sudden relocation has an effect on risk of MS.
