Involvement in diseasei

Retinitis pigmentosa 77 (RP77)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of retinitis pigmentosa, a retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP77 inheritance is autosomal recessive.
