Which feature is typically NOT associated with fetal alcohol syndrome?

Fetal Alcohol Syndrome (FAS) is characterized by a specific set of physical and neurological features that arise from prenatal alcohol exposure. One of the hallmark manifestations includes distinct facial features. While midface hypoplasia, a thin vermillion border, and strabismus are common features associated with FAS, large palpebral fissures are not typically seen in this context.

In fact, individuals with FAS often present with a smooth philtrum, thin upper lip, short palpebral fissures, and other defects that are seen on the spectrum of dysmorphia resulting from alcohol exposure. The presence of large palpebral fissures would not align with the classic features of FAS. Therefore, identifying large palpebral fissures as not associated with fetal alcohol syndrome highlights a crucial aspect of recognizing the classic facial dysmorphisms often used for diagnosis. Understanding these characteristics is essential for professionals in neonatal care and assessment of developmental disorders.
