👉 Cabrera's disease is a genetic disorder characterized by severe, progressive loss of vision in the central visual field (VHF) and peripheral vision (VLP). It is caused by mutations in the gene encoding the protein responsible for the transmission of light signals to the retina. This mutation leads to a disruption in the function of a specific protein called CRYBP, which plays a crucial role in the transmission of light signals from the visual cortex to the brain.
