Quizplus · Accepted Answer

The boy's rapid growth and normal body proportions suggest hypersecretion of growth hormone, which can lead to gigantism if it occurs before the closure of the growth plates. The below-normal mental cognition could also be related to this condition, as it can have various systemic effects.
