Objectives

Narrative objectives1

Coats disease is a congenital nonhereditary retinal vascular disorder characterized by retinal telangiectasia and exudative retinopathy. But etiology is unknown. Although Coats disease is caused by vascular malformations such as capillary aneurysms and telangiectasias in the peripheral retinal vessels, intracranial vascular abnormalities may exist in the same central nervous system. There have been no studies that have closely examined intracranial blood vessels in Coats disease patients. In this study, we will examine intracranial vascular lesions in patients with Coats disease. Recently, the RNF213 gene has been identified as a susceptibility gene for moyamoya disease. The gene is associated with systemic vascular diseases such as atherosclerotic intracranial artery stenosis, pulmonary artery stenosis, and coronary artery stenosis. The RNF213 gene may be involved in the formation of Coats disease as the same vascular disease. In this study, we performed whole exosome sequencing analysis of peripheral blood DNA from patients with Coats disease to determine new causative genes of Coats disease, including the RNF213 gene.

Basic objectives -Others

The prevalence of cerebrovascular abnormalities in patients with Coates' disease will be investigated by magnetic resonance imaging (MRI) of the head.
We will conduct whole exosome sequencing analysis of peripheral blood-derived DNA in patients with Coates' disease to identify RNF213 mutations and search for disease-causing gene mutations in Coates' disease.
