Prevalence of cleft palate in CdLS

What is the prevalence of submucous cleft or other clefts in CdLS?

SAC approved answer

Cleft palates are quite common in children with CdLS. Submucous cleft palates are difficult to detect at times. There are openings in the roof of the mouth that are covered over by skin. We believe the prevalence of cleft palate to be 26%, including submucous cleft palates. About one third of the cleft palates are submucous. RM/ TK 7-13-10
