New recognized ophthalmic morphologic anomalies in CHARGE syndrome caused by the R2319C mutation in the CHD7 gene

Ophthalmic Genet. 2008 Jun;29(2):79-84. doi: 10.1080/13816810801918391.

Abstract

Purpose: To report new findings in the CHARGE syndrome with phenotypic anomalies associated with the R2319C mutation in the CHD7 gene.

Methods: Fundoscopic photography, ultrasonography, fluorescein angiography, optical coherence tomography (OCT). Mutational analysis of the CHD7 gene in lymphocyte DNA.

Results: Large pale optic discs with a fibrous elevation and colobomata and arterio-venous anastomoses with enlarged veins in optic discs were detected. OCT revealed numerous flat cystic spaces. The genetic study revealed the R2319C mutation in the CHD7 gene.

Conclusions: The CHARGE syndrome associated with the R2319C mutation in the CHD7 gene comprised: cystic spaces in the colobomatous optic disc and intrapapillary arterio-venous anastomoses.
