Syndromology Major
Significant functional or cosmetic impact Heart defect, abnormal brain formation, cleft
lip/palate Minor
No major functional or cosmetic impact

Patterns Sequence
Multiple defects from a single malformation Pierre Robin
Syndrome All components are pathologically related Trisomy 21 or Fetal Alcohol
Association Occur together more frequently VATER/VACTERL CHARGE

Syndromes More prevalent than you think Look for abnormalities minor
malformations may indicate that major ones may also exist
More than one family member may be affected
Identification should not be underestimated Better care Better counseling Better Surveillance
