What features are characteristic of Fetal Hydantoin Syndrome?

Fetal Hydantoin Syndrome (FHS) is a condition caused by fetal exposure to the anticonvulsant medication phenytoin (Dilantin) during pregnancy. It is characterized by a distinctive set of facial features and growth patterns. The correct choice highlights a short, wide nose and hypertelorism, which are indeed key components of the syndrome.

Hypertelorism refers to an increased distance between the eyes, resulting in a broader appearance of the face. This feature, combined with the short and wide nose, aligns with the typical phenotypic presentation observed in individuals affected by FHS. Other characteristics can include developmental delays and growth deficiencies, as well as potential limb and craniofacial abnormalities.

The other answer choices describe features that do not accurately represent the classic presentation of Fetal Hydantoin Syndrome. For instance, the features described in the other options—such as a narrow face and large ears, or long limbs and a broad forehead—are not characteristic of FHS and instead align with different genetic or environmental syndromes. Understanding the specific facial and skeletal features assists in making a correct diagnosis and guiding management in affected individuals.
