A child is born with a mutation that causes dehydrocholesterol to be unreactive when exposed to sunlight. This will lead to the child developing rickets.

Question

Quizplus · Accepted Answer

Dehydrocholesterol is a precursor molecule for the production of vitamin D3 in the skin upon exposure to sunlight. If this molecule is unreactive to sunlight, the child will not be able to produce adequate amounts of vitamin D3, which is essential for the proper absorption of calcium and phosphorus in the body. This can lead to the development of rickets, a condition characterized by weak and brittle bones.
