Purpose To describe a patient with DiGeorge syndrome in association with familial exudative vitreoretinopathy (FEVR). Design Observational case report. Participants A newborn female and her parents. Methods Family members were examined by slit-lamp biomicroscopy and indirect ophthalmoscopy. Deletion mapping was performed by fluorescent in situ hybridization and genotyping. Mutation screening was undertaken by direct sequencing. Main Outcome Measures The presence or absence of a microdeletion on chromosome 22q11.2 in the patient and her parents and mutation screening of FZD4 and LRP5 in the patient. Results The patient had classical features of DiGeorge syndrome and FEVR. A de novo microdeletion on chromosome 22q11.2 was found in the patient, confirming the diagnosis of DiGeorge syndrome. No mutations were identified in the known FEVR genes. Conclusions Patients with DiGeorge syndrome should have a dilated retinal examination to look for signs of FEVR. Chromosome 22q11.2 may represent a novel locus for FEVR. Financial Disclosure(s) The author(s) have no proprietary or commercial interest in any materials discussed in this article. |
