Assessment of RS1 in X-linked juvenile retinoschisis and sporadic senile retinoschisis

Clin Genet. 1999 Jun;55(6):461-5. doi: 10.1034/j.1399-0004.1999.550611.x.


The RS1 gene is the causative gene in X-linked juvenile retinoschisis (RS). We have screened this gene for mutations in 13 patients with RS and in 7 probands with senile retinoschisis, a sporadic, later-onset form of retinoschisis. Mutations were detected in all RS patients. Of the 11 different mutations identified, six have been reported previously and live are novel. We did not find mutations in any of the senile retinoschisis patients and conclude that senile retinoschisis is not the result of germline mutations in the RS1 gene.
