A 5-year-old, mentally retarded boy is brought to the city from a rural community for evaluation. A careful history reveals mental retardation in a number of other family members, especially the males. Physical examination is remarkable for a long face with large ears, a large jaw, and bilateral enlargement of the testes. This presentation is suggestive of
(A) Down syndrome
(B) Edwards syndrome
(C) Fragile X syndrome
(D) Klinefelter syndrome
(E) Turner syndrome
