Lens fibre cell differentiation - A link with apoptosis?

abstract：AIM/BACKGROUND:A 1-bp deletion (1147delA) in the SAG (also known as arrestin or S-antigen) gene is the most frequently seen mutation in Japanese patients suffering from Oguchi disease, a recessively inherited stationary night blindness. We investigated macular function in a patient with Oguchi disease with the 1147delA...
