The authors would like to report an error in Fig 4 where RP1 in the originally published figure should have been RP2 as in the corrected figure below. [Figure presented] Fig. 4. Causative genes and their relative proportions in Retinitis Pigmentosa (RP). The inheritance of RP consists of autosomal dominant (ad), autosomal recessive (ar), X-linked (xl) and unknown patterns. The causative genes for adRP are Rho, RPRF, PRPH2, RP1, IMPDH1 and PRPF8; for arRP, USH2A, ABCA4, PDE6A, and PDE6B and RPE65; for xlRP, RPGR and RP2. The authors would like to apologize for any inconvenience caused.
