Disclosures Speaker’s Bureau for Alcon

Syndromology Major

Significant functional or cosmetic impact Heart defect, abnormal brain formation, cleft

lip/palate Minor

No major functional or cosmetic impact

Etiology Environmental (Teratogenic)

Alcohol exposure Chromosomal

Single gene Multiple gene

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

Branchio-Oto-Renal (Melnick-Fraser)

Branchial cleft sinuses Hearing Loss

Sensorineural but may be mixed Renal Dysplasia (12-20%) Autosomal Dominant

1 in 40,000 Births Variable penetrance Associatied with 8q Facial Palsy/Lacrimal duct

Treacher Collins (Mandibulofacial Dysostosis)

Autosomal Dominant 1 in 50,000 births 5q Abnormal structures of 1st and 2nd

Branchial arches, grooves and pouch. Small, absent, or low set ears Micrognathia Cleft Palate (35%) Normal Intelligence

Nagers(Acrofacial Dysostosis)

Malar Hypoplasia Down-slanting palpebral fissures Absence of lower eyelashes Atretic External Auditory Canals Conductive Hearing Loss Normal cognition and development Localization to 9q Limb abnormalities, particularly

absent thumbs

Velo-Cardio-Facial(Shprintzen)

High Arched/Cleft palate Broad nasal root Cognitive impairment Cardiac anomalies Velopharyngeal Insufficiency (VPI) Immunologic deficiencies 22q11 deficiency, Autosomal Dominant Feeding difficulties Hypocalcemia

Down’s Syndrome Trisomy 21 Stenotic ear canals/Low set ears COME/Eustachian tube dysfunction Middle ear anomalies Delayed Speech Obstructive Sleep Apnea Macroglossia Narrowed subglottis/trachea Cardiac defects

Mucopolysaccharidoses Lysosomal Storage Disease 7 distinct types Hurlers, Hunters, Sanfillipo Morquio, Maroteaux-Lamy Coarse facial features AIRWAY ISSUES!!!!! Obstructive Sleep Apnea Enzyme Replacement for

types I,II, and VI

CHARGE Syndrome Coloboma Heart Anomalies Atresiae Chonae Retardation Genital Anomalies Ear Anomalies ~60% defect of CHD7 gene(chromosome

8)

VATER(VACTERL) Association Vertebral Anomalies Anal Cardiac defects Tracheo-esophageal Fistula Renal/Radial anomalies Limb defects No specific genetic pattern or inheritance Incidence 16/100,000

Stickler’s Syndrome Midface Hypoplasia Cleft palate (Pierre Robin) Depressed Nasal Bridge Hearing Loss (15%) Dental Anomalies Mitral Valve Prolapse Genetic Sequencing is available Joint dysplasia/

hyperextensibilty

Kartagener’s Syndrome Immotile Cilia Situs Inversus Sinusitis Bronchitis/bronchiectasis Otitis Media Autosomal Recessive Genetically heterogenous

Craniosynostosis Crouzon’s

Midface hypoplasia, coronal suture synostosis Apert’s

Bicoronal synostosis, midface hypoplasia, orbital hypertelorism, polydactyly

Saethre-Chotzen Bilateral coronal synostosis , variable midface

hypoplasia, low set hairline , cleft palate Pfeiffer

Multiple types with synostosis and most with limb abnormalities

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
