ABSTRACT
AIM:
To identify the mutations in RS1 gene associated with typical phenotype of X-linked juvenile retinoschisis (XLRS) and a rare condition of concomitant glaucoma.METHODS:
Complete ophthalmic examinations were performed in the proband. The coding regions of the RS1 gene that encode retinoschisin were amplified by polymerase chain reaction and directly sequenced.RESULTS:
The proband showed a typical phenotype of XLRS with large peripheral retinal schisis in both eyes, involving the macula and combined with foveal cystic change, reducing visual acuity. A typical phenotype of recurrent glaucoma with high intraocular pressure (IOP) and reduced visual field was also demonstrated with the patient. Mutation analysis of RS1 gene revealed R102W (c.304C>T) mutations in the affected male, and his mother was proved to be a carrier with the causative mutation and another synonymous polymorphism (c.576C>CT).CONCLUSION:
We identified the genetic variations of a Chinese family with typical phenotype of XLRS and glaucoma. The severe XLRS phenotypes associated with R102W mutations reveal that the mutation determines a notable alteration in the function of the retinoschisin protein. Identification of the disease-causing mutation is beneficial for future clinical references.
