Hereditary diseases

Description
Progressive Retinal Atrophy (PRA) is the general name for a group of retinal diseases that damage photoreceptor cells (rods and cones) until their death.

A mutation in the RPGRIP1 gene (retinitis pigmentosa GTPase regulator-interacting protein 1 gene) leads to progressive retinal atrophy cord1 (PRA cord1). This type of progressive retinal atrophy is characterized by cone-rod dystrophies (hence the name of the disease - cord1). The first signs of the disease, which can be recorded ophthalmologically, appear at the age of about six months. DNA test detects PRA cord1 from the first days of life.
