Our studies demonstrate that an R17C mutation in PRCD does not affect membrane association or palmitoylation. However, the mutation does affect PRCD protein stability and trafficking to the photoreceptor OS, which may be why this mutation is associated with RP in human patients.

We are focusing on identifying genes causing autosomal dominant form of RP and elucidating underlying pathogenic mechanisms. We show that missense mutations in CAIV , a gene not expressed in retina including photoreceptors or RPE, are responsible for an autosomal dominant form of retinitis pigmentosa (RP17).

After thirty years of research, the genetic defect that causes the eye disease retinitis pigmentosa type 17 (RP17) has finally been discovered. Molecular geneticists Susanne Roosing and Suzanne de Bruijn located the gene defect by examining the genetic material (DNA) of a large Dutch family that had been forwarded by physicians from the Department of Ophthalmology.
