BRIEF DESCRIPTION
TTC8 retinitis pigmentosa is a type of retinitis pigmentosa (RP) that's caused by a mutation in the TTC8 gene. It's also known as RP51. Related conditions include 1.) Bardet–Biedl syndrome (BBS), a condition that can be caused by a mutation in the TTC8 gene. Retinitis pigmentosa is one of the primary features of BBS8; 2.) Progressive retinal atrophy (PRA), the canine equivalent of retinitis pigmentosa. A deletion in the canine TTC8 gene can cause PRA.
Symptoms include night blindness, difficulty adjusting to light changes, trouble seeing in low light or bad weather, tunnel vision, difficulty seeing colors, especially blue, gradual vision loss, partial or complete, and clumsiness. At this time, there are no cure for retinitis pigmentosa, but medications can help treat complications.
