Two genes in the region have previously been associated with inherited retinopathies in humans; Spermatogenesis associated protein 7 (SPATA7) has been associated with juvenile RP and LCA [21], and tetratricopeptide repeat domain 8 (TTC8) with RP as well as Bardet-Biedl Syndrome (BBS) [22–24]. The gene discussed is TTC8; the disease is retinitis pigmentosa 1.
