Associated syndromes in patients with Pierre Robin Sequence.

OBJECTIVES

Classically, Pierre Robin Sequence (PRS) is a triad of micrognathia, glossoptosis, and airway obstruction, although frequently associated with cleft palate. Current literature reports that Stickler syndrome is the most common syndrome associated with PRS, and 22q11 deletion syndrome (22q11 DS) as the second most common. This study identifies associations between PRS and genetic syndromes.

METHODS

A retrospective chart review was performed to identify patients diagnosed with PRS over a 10-year period from 4/1/2007 to 4/1/2017 at a tertiary children's hospital.

RESULTS

4,052 consecutive charts were reviewed and 234 patients had a diagnosis of PRS confirmed with the triad of micrognathia, glossoptosis, and airway obstruction. Of note, all of these patients had cleft palate. Of the 234 patients with PRS, 65 patients had syndromic diagnoses (28%). One patient had 22q11 DS (0.43%), and 31 patients had Stickler syndrome (13.2%). Additionally, 3 patients had central hypoventilation syndrome, 3 patients had Duane syndrome, 2 patients had Cornelia de Lange syndrome, 2 patients had Emanuel syndrome, 2 patients had Gordon syndrome, 2 patients had Mobius syndrome, 2 patients had Nager syndrome. Multiple other syndromes were identified, but occurred in isolated cases.

CONCLUSION

This study supports literature that PRS is most commonly associated with Stickler Syndrome but rarely associated with 22q11 DS given that only 1 patient had both PRS and 22q11 DS.
