Summary
Warfarin exposure during gestation caused significant fetal abnormalities, including nasal hypoplasia and brachydactyly (shortened phalanges). These teratogenic effects in humans result from abnormal cartilage development, not hemorrhage.
Area of Science:
- Developmental biology
- Teratology
- Human embryology
Background:
- Warfarin is a widely used anticoagulant.
- Previous studies suggest potential teratogenic effects of warfarin.
- Understanding the specific mechanisms of warfarin teratogenicity is crucial.
