The frequency of mutations found in the Swedish patient group indicates that defects in the peripherin/RDS gene might be a more common cause of autosomal dominant retinitis pigmentosa than was thought previously.}, author = {Ekström, Ulf and Ponjavic, Vesna and Andréasson, Sten and Ehinger, Berndt and Nilsson-Ehle, Peter and Abrahamson, Magnus}, issn = {1366-8714}, language = {eng}, number 2008-03-01 · Peripherin/rds is an integral membrane glycoprotein, mainly located in the rod and cone outer segments. The relevance of this protein to photoreceptor outer segment morphology was first demonstrated in retinal degeneration slow ( rds) mice. Thus far, over 90 human peripherin/RDS gene mutations have been identified.

1997-11-01 · Haploinsufficiency because of a null mutation in the gene encoding peripherin/rds has been thought to be the primary defect associated with the photoreceptor degeneration seen in the retinal degeneration slow (rds) mouse. Abstract. Purpose: To measure the proportion of cases of retinitis pigmentosa (RP) caused by mutations in the peripherin/RDS (RDS) and ROM1 genes. Methods: The single-strand conformation polymorphism (SSCP) method was used to analyze 227 unrelated patients with dominant or recessive RP for mutations in the RDS gene and an overlapping In 1987, a second distinct peripherally located retinal rod protein was also given the name peripherin. To distinguish between the two, this second protein is referred to peripherin 2 or peripherin/RDS (retinal degeneration slow) for its location and role in retinal disease.

Previous studies indicate that the protein, peripherin or peripherin/rds, is localized along the rim of mature disks of rod outer segments. A mutation in the gene for this protein has been reported to be responsible for retinal degeneration in the rds mouse. The PRPH2 gene (also known as RDS) provides instructions for making a protein called peripherin 2. This protein plays an important role in normal vision. Peripherin 2 is found in the retina, the light-sensitive tissue that lines the back of the eye. Peripherin/rdsand rom-1 have structural roles in morphogenesis and stabilization of the outer segment, but little is known about their transport and sorting to the rod outer segment. Peripherin/rdsand rom-1 trafficking were studied in several knockout and transgenic animal models.

Detergent soluble Crds2 is a more distant homologue of mammalian RDS but closer as to Xenopus rds The RDS gene codes for the protein peripherin‐RDS, which is an integral membrane glycoprotein found in the outer segment of both rod and cone photoreceptor cells. It is thought to function as a structural protein involved in the maintenance of the flattened form of the disc lamellae. Peripherin/rds and Rom1 trafficking was maintained in rhodopsin-knockout mice, suggesting that rim proteins and rhodopsin have separate transport pathways. The presence of truncated peripherin/rds-GFP in the outer segment supported previous evidence that peripherin/rds mice form homotetramers for outer segment targeting. Peripherin/Rds is a tetraspanning membrane protein that has been implicated in photoreceptor outer segment morphogenesis and inherited retinal degenerative diseases.

The data also provide an empirical basis with which to compare rds/1 mice to patients heterozygous for one or another dominantly inherited peripherin/rds mutation. Cyclic GMP‐Gated Channel and Peripherin/rds‐rom‐1 Complex of Rod Cells Robert S. Molday Department of Biochemistry and Molecular Biology, University of British Columbia, Faculty of Medicine, 2146 Health Science Mall, Vancouver BC, Canada V6T 1Z3 CONCLUSIONS: The peripherin/RDS gene mutation F211L is associated with a clinical phenotype and includes early loss of rod function and successive reduction of cone function with increasing age, but impressively well-preserved visual acuity and visual fields in young and middle-aged patients and moderately reduced vision in the old patient. Abstract : Rds/peripherin is an integral membrane glycoprotein that is present in the rims of photoreceptor outer segment disks. In mammals, it is thought to stabilize the disk rim through heteroph Macular appearance by means of OCT and electrophysiology in members of two families with different mutations in RDS (the peripherin/RDS gene).

RDS/Peripherin and ROM-1 are two transmembrane proteins present in photoreceptor outer segment disc membranes. While RDS/Peripherin is present in rods and cones, ROM1 is restricted to rods only .The proteins form heterodimers in rods as well as homodimers in cones.
