Which symptom is specifically associated with facial defects in Fetal Alcohol Syndrome?

Fetal Alcohol Syndrome (FAS) is a condition that can occur in individuals whose mothers consumed alcohol during pregnancy. One of the hallmark characteristics of FAS is the presence of abnormal facial features, which are specifically associated with the syndrome. These facial defects can include a smooth philtrum (the area between the nose and upper lip), thin upper lip, and small palpebral fissures (the openings between the eyelids).

The abnormal facial features are critical in the diagnosis of FAS, as they provide visual markers that can indicate prenatal exposure to alcohol. Thus, recognizing these distinctive traits is essential for healthcare professionals in both identifying FAS and providing appropriate interventions.

The other options listed do not relate specifically to the facial defects characteristic of FAS. For instance, increased facial hair and heightened sensitivity to sunlight do not have a known association with facial defects caused by prenatal alcohol exposure. Therefore, the correct answer highlights the significance of abnormal facial features in identifying Fetal Alcohol Syndrome.
