What is a classic symptom of fetal alcohol syndrome?

Shortened palpebral fissures are indeed a classic symptom of fetal alcohol syndrome (FAS). This condition results from prenatal exposure to alcohol, leading to a characteristic pattern of facial anomalies. The shortened palpebral fissures are a key identifying feature and significantly contribute to the diagnosis of FAS. Other physical features associated with FAS often include a smooth philtrum and thin upper lip, but the shortened palpebral fissures are particularly notable and are specifically highlighted as diagnostic criteria.

When assessing for symptoms of fetal alcohol syndrome, clinician awareness of these characteristic facial features is critical, as they can help in early identification and management of affected individuals. These facial features result from the teratogenic effects of alcohol on the developing fetus, particularly affecting the growth and development of facial structures. Recognizing these signs can lead to prompt intervention and support for families affected by this syndrome.
