Ophthalmic Findings Associated with NEDD4L-related Disorder

Abstract

Pathogenic variants in the NEDD4L gene are associated with a very rare neurodevelopmental disorder characterized by periventricular nodular heterotopia, developmental delay, 2-3 toe syndactyly, and cleft palate. Ophthalmic findings associated with this disorder have not been well described in literature. We have summarized the clinical findings that have been reported in this disorder previously and highlight a novel ophthalmic finding of foveal hypoplasia in a new case of NEDD4L-related disorder.
