My brother and I are twins. We both have XLCSNB and but I have 50% and my brother has 100%. We have an older brother with 15/20 in both eyes with no other complications. The disease came from our mom's side, and she has a sister and an aunt and uncle who also carried the gene. Our aunt has two kids who don't have the disease. If you could get back to me about latest research for XLCSNB that would be great.

Summarized question: What is the latest research for X-linked congenital stationary night blindness?
