oculo-auricular syndrome
Friday 25 April 2008
The oculo-auricular syndrome is characterized by ophthalmic anomalies (microcornea, microphthalmia, anterior-segment dysgenesis, cataract, coloboma of various parts of the eye, abnormalities of the retinal pigment epithelium, and rod-cone dystrophy) and a particular cleft ear lobule.
Etiology
NKX5-3 gene germline mutations
Morpholino knockdown expression of the zebrafish nkx5-3 induced microphthalmia and disorganization of the developing retina, thus confirming that this gene represents an additional member implicated in axial patterning of the retina.
