abstract：:Retinoschisin (RS1) is a retina-specific secreted protein encoding a conserved discoidin domain sequence. As an adhesion molecule, RS1 preserves the retinal cell architecture and promotes visual signal transduction. In young males, loss-of-function mutations in the X-linked retinoschisis gene (RS1) cause X-linked reti...
