Bifid tongue, corneal clouding, and Dandy-Walker malformation in a male infant with otopalatodigital syndrome type 2.

We report on a male infant with otopalatodigital syndrome type 2 (OPD2) associated with a novel c.514C>G FLNA mutation and unusual clinical features including bifid tongue and congenital corneal clouding. Bifid tongue and congenital corneal clouding have each only been described once previously in a patient with OPD2, and this is the first description of Dandy-Walker malformation (DWM) in OPD2. The presence of these clinical findings in a mutation-confirmed case of OPD2 supports the notion that corneal clouding, bifid tongue, and DWM are part of the constellation of abnormalities caused by mutations in FLNA.
