Ring dermoid of cornea
Definition:
The ring dermoid of the cornea (RDC) is an autosomal dominantly inherited syndrome characterised by bilateral annular limbal dermoids with corneal and conjunctival extension. A mutation in PITX2 has been identified in the individuals affected by the RDC. PITX2 encodes a homeodomain transcription factor required for normal development of multiple organs, including eye, heart, and pituitary.
