High impact information on RP1

 

Chemical compound and disease context of RP1

 

Biological context of RP1

  • They emphasise that caution is required in genetic counselling of RP families, particularly in the absence of any molecular genetic analysis [20].
  • Retinitis pigmentosa families showing apparent X linked inheritance but unlinked to the RP2 or RP3 loci [20].
  • Microsatellite analysis of Family 1 revealed that the RP in the family was linked to the RP3 locus [2].
  • Due to the complexity in phenotype and genetics, and the fact that RP is untreatable, genetic testing for presymptomatic diagnosis of RP is controversial [3].
  • A large number of mutations cause RP, and they can be deletions, insertions, or substitutions that cause missense mutations or truncations [3].
 

Anatomical context of RP1

  • Retinitis pigmentosa (RP) is a heterogeneous group of retinal dystrophies characterized by photoreceptor cell degeneration [21].
  • Data obtained with highly conserved yeast homologues suggest that the EB1/RP1 protein family promotes cytoplasmic microtubule dynamics and contributes to the sensor mechanism controlling the cytokinesis checkpoint during mitosis [22].
  • Based on linkage data from the CEPH (Paris) reference families and physical mapping information from a somatic cell hybrid panel of chromosome 8 fragments, the most likely order for four of these five loci and the diseases locus is 8pter-LPL-D8S5-D8S87-PLAT-RP1 [4].
  • Consistent with expression of RPGR in rods and cones, our results show that mutations in RPGR, in addition to X-linked RP, can also cause cone-specific degeneration [23].
  • Mutations in the crumbs homologue 1 (CRB1) gene cause a specific form of retinitis pigmentosa (RP) that is designated "RP12" and is characterized by a preserved para-arteriolar retinal pigment epithelium (PPRPE) and by severe loss of vision at age <20 years [24].
 

Associations of RP1 with chemical compounds

  • The allelic frequency of intron 3 RP1 was significant different in the patients with discoid rash when compared to patients without this clinical feature (OR = 3.70, 95% CI 2.04-6.72, chi2 test, P = 0.029) [25].
  • Positional cloning of the gene for X-linked retinitis pigmentosa 3: homology with the guanine-nucleotide-exchange factor RCC1 [26].
  • Notably, mutations that alter this arginine codon cause familial retinitis pigmentosa [27].
  • Here we report an association between a missense coding region polymorphism Asn985Tyr in the retinitis pigmentosa 1 gene ( RP1) and plasma triglyceride (TG) levels in 332 adult individuals from an east-central area of Japan. Age and gender-adjusted levels of LDL-cholesterol, TG, and HDL-cholesterol were analyzed [28].
  • A heterozygous novel C253Y mutation in the highly conserved cysteine residues of ROM1 gene is the cause of retinitis pigmentosa in a Spanish family [29]?
 

Physical interactions of RP1

  • RPGRIP1 encodes the retinitis pigmentosa GTPase interacting protein 1 and interacts with RPGR, the latter represents the major X-linked RP (XRRP) gene, as it accounts for 70-80% of the XRRP patients and up to 13% of all RP patients [30].
  • The protein carries 11-cis-retinal and/or 11-cis-retinol as endogenous ligands in the RPE and retina and mutations in human CRALBP that destroy retinoid binding functionality have been linked to autosomal recessive retinitis pigmentosa [31].
  • Eleven single-point mutations associated with retinitis pigmentosa at and in the proximity to the retinal binding pocket of rhodopsin have been modeled in silico and their spectra calculated with the NDOL (Neglect of Differential Overlap accounting L azimuthal quantum number) a priori method [32].
 

Regulatory relationships of RP1

 

Other interactions of RP1

  • The COD1 locus originally was localized, by the study of three independent families, to a region between Xp11.3 and Xp21.1, encompassing the retinitis pigmentosa (RP) 3 locus [35].
  • The distinct RPE abnormalities observed in RP12 patients suggest that CRB1 mutations trigger a novel mechanism of photoreceptor degeneration [36].
  • A novel locus (RP24) for X-linked retinitis pigmentosa maps to Xq26-27 [37].
  • The resultant LCA array allows simultaneous detection of all known disease-associated alleles in any patient with early-onset RP [38].
  • Multipoint linkage analysis, using a simplified pedigree structure for the family (which contains 192 individuals and two inbreeding loops), gave a maximum lod score of 12.2 for RP1 at a distance 8.1 cM proximal to PLAT in the pericentric region of the chromosome [4].
