Question

Quizplus · Accepted Answer

The physical characteristics described (round face, broad, flat nose, small folds of skin at inside corners of eyes, protruding tongue, small squarish hands, and short arms and legs) are all common features of individuals with Down syndrome. Additionally, the presence of intellectual developmental disorder and heart and respiratory problems are also consistent with this condition. Klinefelter's syndrome and fragile X syndrome may cause intellectual and developmental disability, but they do not typically have the same physical characteristics described. Phenylketonuria does not cause the physical characteristics or heart and respiratory problems described.
