Fig. 7From: A novel mutation in the CRYAA gene associated with congenital cataract and microphthalmia in a Chinese familyProtein sequence of αA-crystallin. There are 13 arginine residues (red or green) in human αA-crystallin. Nine of these 13 arginine residues (red) are hot spots for mutations, which eventually lead to congenital cataractsBack to article page
