Table 3. γD-crystallin mutations, related phenotypes and functional changes
Seven disease-causing mutations of GRYGD have been identified for congenital cataract with different phenotypes. Unlike most of the missense mutations without causing any protein conformation changes, the novel truncated G165fs showed altered protein properties.
