Fetal warfarin syndrome (FWS) is a rare condition which can occur as a result of fetal exposure to maternal ingestion of warfarin during pregnancy.
Reported clinical features include:
- facial anomalies
- skeletal anomalies
- central nervous system
Warfarin is a teratogenic drug. The increased risk of birth defects occurs particularly with warfarin use during ~6-9 weeks gestation.
- some features (particularly skeletal) can mimic that of chondrodysplasia punctata
