| Retinal disorders v2.219 | BEST1 |
Eleanor Williams changed review comment from: Review of mode of inheritance: Macular dystrophy, vitelliform, 2 OMIM:153700 - many heterozygous cases reported OMIM also lists Bestrophinopathy, autosomal recessive OMIM:611809 and Retinitis pigmentosa, concentric and Retinitis pigmentosa-50 OMIM:613194 but with no inheritance pattern listed. Reports for 11 biallelic cases: PMID: 18179881 Burgess et al 2008 - report on the analysis of the BEST1 gene in 7 affected individuals from 5 unrelated families of European ethnicity. Clinical electrophysiology of affected individuals showed abnormal full-field ERGs in addition to a severe reduction in the electrooculogram (EOG) light rise analogous to that seen with dominant BEST1 mutations that cause both Best disease and autosomal-dominant vitreoretinochoroidopathy. In all families homozygous or compound het variants in BEST1 were found (6 missense, 1 nonsense). 10 asymptomatic heterozygotes were examined in detail and were found to have a normal retinal examination, ERG responses, and EOG light rise. PMID: 34327816 - Nowomiejska et al 2021 - in retrospective variant-phenotype analysis they report 6 patients with either homozygous or compound het variants in BEST1, aswell as 24 patients with heterozygous variants.; to: Review of mode of inheritance: Macular dystrophy, vitelliform, 2 OMIM:153700 - many heterozygous cases reported OMIM also lists Bestrophinopathy, autosomal recessive OMIM:611809 and Retinitis pigmentosa, concentric and Retinitis pigmentosa-50 OMIM:613194 but with no inheritance pattern listed.
