Description : X-linked retinoschisis (XLRS) is a retinal dystrophy that leads to schisis (splitting)
of the neural retina leading to reduced visual acuity in affected men. The condition
accounts for almost all congenital retinoschisis, with occasional reports of autosomal
dominant retinoschisis (see 180270) making up the remainder. The split in the retina
occurs predominantly within the inner retinal layers and is very different from retinal
detachment, which is a split between the neural retina and the retinal pigment epithelium.
In general, carrier females remain asymptomatic (summary by Sikkink et al., 2007).;
Inheritance : X-linked recessive;
Molecular basis : Caused by mutation in the retinoschisin gene (RS1, 300839.0001);
