    Summary
    This summary is machine-generated.

    Maternal valproic acid therapy during pregnancy may cause birth defects. This study identifies a distinct pattern of facial and growth abnormalities in infants exposed to valproic acid, highlighting teratogenic risks.

    Area of Science:

    • Teratology
    • Developmental Biology
    • Pharmacology

    Background:

    • Determining the teratogenic risk of maternal valproic acid therapy is challenging due to limited data on women using it as monotherapy.
    • Previous reports suggest an increased incidence of neural tube defects and dysmorphic features associated with prenatal valproic acid exposure.

    Observation:

    • This case report details a patient with morphogenesis defects solely linked to valproic acid exposure.
    • The patient exhibits a dysmorphic facial phenotype, including hypertelorism, a prominent forehead, a flat nasal bridge, and micrognathia.

    Findings:

    • A unique finding in this patient is hypoplasia of the lateral margins of the zygomatic arches.
    • The observed features align with a previously suggested clinical phenotype for prenatal valproic acid exposure, including growth deficiency.

    Implications:

    • This study contributes to understanding the specific teratogenic effects of valproic acid, aiding in risk assessment for pregnant epileptic women.
    • Further research into valproic acid pharmacokinetics during pregnancy and in neonates is warranted.
