Which condition results from maternal alcohol consumption during pregnancy?

• A. Fetal Alcohol Syndrome
• B. Down Syndrome
• C. Fragile X Syndrome
• D. Prader-Willi Syndrome

Answer: (A)

Alcohol acts as a teratogen, so exposure of the developing fetus to alcohol during pregnancy can disrupt growth and brain development. This exposure can produce Fetal Alcohol Spectrum Disorders, with Fetal Alcohol Syndrome being the classic and most recognized form. The syndrome typically includes growth deficiency before and after birth, facial features such as a smooth philtrum, a thin upper lip, and small eye openings, and central nervous system problems like cognitive and behavioral impairments and microcephaly. The combination of growth failure, distinctive facial characteristics, and CNS dysfunction is what makes Fetal Alcohol Syndrome the best answer for conditions arising from maternal alcohol use. Down syndrome is due to a chromosomal alteration (trisomy 21) and has a different facial profile and systemic features. Fragile X syndrome results from a genetic mutation on the X chromosome and shows typically with intellectual disability and behavioral traits. Prader-Willi syndrome is a genetic imprinting disorder with hypotonia, hyperphagia, and obesity tendencies. The important point is that alcohol exposure during pregnancy can lead to Fetal Alcohol Syndrome, whereas the others arise from genetic or chromosomal factors.
