Ophthalmic and Systemic Findings in Interstitial Deletions of Chromosome 14q: A Case Feport and Literature Review

Abstract

We report a patient with clinical anophthalmia, partial eyelid fusion and a hypoplastic socket on the right. The left eye has microphthalmia involving the anterior and posterior segments, microcornea, iris coloboma, chorioretinal dysgenesis, macular dysplasia, absence of retinal vessels, and optic nerve aplasia. Systemic abnormalities include microcephaly, bilateral hearing loss, and duodenal atresia. Electrophysiologic testing showed no response from either eye. Cytogenetic testing revealed a de novo interstitial deletion of chromosome 14q22.3q23.1. The literature of similar interstitial deletions and ongoing candidate gene studies are reviewed.
