Paul De Fazio gene: CEP162 was added gene: CEP162 was added to Retinitis pigmentosa_Autosomal Recessive/X-linked. Sources: Literature Mode of inheritance for gene: CEP162 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: CEP162 were set to 36862503 Phenotypes for gene: CEP162 were set to Retinitis pigmentosa MONDO:0019200, CEP162-related Penetrance for gene: CEP162 were set to unknown Review for gene: CEP162 was set to AMBER gene: CEP162 was marked as current diagnostic Added comment: 2 patients from reportedly unrelated consanguineous Moroccan families with the same homozygous frameshift variant reported with late-onset retinal degeneration. Patient 1 was diagnosed with RP at age 60, patient 2 at age 69. Both reported loss of visual acuity in the years prior. Immunoblotting of cell lysates from patient fibroblasts showed that some mutant transcript escaped NMD. Functional testing showed that the truncated protein could bind microtubules but was unable to associate with centrioles or its interaction partner CEP290. Patient fibroblasts were shown to have delayed ciliation. Mutant protein was unable to rescue loss of cilia in CEP162 knockdown mice supporting that the mutant protein does not retain any ciliary function, however additional data supported that the truncated protein was able to bind microtubules and function normally during neuroretinal development. The authors suggest this likely underlies the late-onset RP in both patients. Rated Amber because only a single variant has been reported in patients who may or may not be related (same ethnic background). Sources: Literature |
