Question

Quizplus · Accepted Answer

Fragile X syndrome is the most likely option because it is characterized by physical features such as a long, thin face and oversized ears. It is also often associated with intellectual disability and hyperactivity. Additionally, individuals with fragile X syndrome commonly avoid eye contact with others. Down syndrome is another possibility, but it is less likely given that individuals with Down syndrome typically have a shorter stature and rounder face. PKU and cretinism do not typically present with the physical features or behaviors described.
