Okay kiddo, let's talk about your eyes and a special protein called retinitis pigmentosa GTPase regulator, or RPGR for short.
So, inside your eyes are little parts called rods and cones that help you see. And RPGR is a protein that helps these rods and cones work properly.
But some people have a problem where their RPGR protein doesn't work the way it's supposed to. This problem is called retinitis pigmentosa, and it can cause them to have trouble seeing things in low light or even go blind.
Scientists are working on ways to fix this problem by studying RPGR and finding ways to make it work better. So someday, we might be able to help people see better even if they have retinitis pigmentosa. Pretty cool, huh?
