BEST1 Antibody

1. hBest1's channel activity in human retinal pigment epithelium is significantly enhanced by adenosine triphosphate in a dose-dependent manner PMID: 30087350
2. two recurrent genetic variations of BEST1 in two Chinese patients with either juvenile-onset BVMD or adult-onset BVMD were identified in this study. These findings expand the mutation spectrum of BEST1 and may aid in genetic counseling as well as prenatal diagnoses of patients with BVMD. PMID: 29115605
3. These results revealed that the disease-causing mechanism of BEST1 mutations is centered on the indispensable role of BESTROPHIN1 in mediating the long speculated Ca(2+)-dependent Cl(-) current in retinal pigment epithelium. PMID: 29063836
4. We describe a highly recognizable and reproducible retinal phenotype associated with a specific BEST1 mutation-p.Ala243Val in vitelliform macular dystrophy. PMID: 28225368
5. We present a consanguineous family of five affected individuals with autosomal recessive bestrophinopathy and four confirmed carriers. Their pedigree was consistent with dominant inheritance and incomplete penetrance. PMID: 28481155
6. We have shown that the two novel combinations of compound heterozygous mutations p.R141H/p.M325T and p.R141H/p.I201T in the BEST1 gene can also lead to the autosomal recessive bestrophinopathy phenotype. PMID: 26333019
7. The findings in this family emphasize the previously noted variability of clinical manifestations in BEST1-associated autosomal dominant vitreoretinochoroidopathy (ADVIRC) and the relevance of FAF and NIA imaging. Cystoid macular edema and vascular leakage can be successfully treated using dorzolamide. PMID: 26771239
8. For patients with Best vitelliform macular dystrophy, single heterozygous BEST1 mutations were identified in 13 patients and compound heterozygous mutations were found in 3 patients. For patients with autosomal recessive bestrophinopathy, biallelic mutations were found in 13 probands and single mutant alleles in six patients. Overall, 36 disease-causing variants (20 novel mutations) of the BEST1 gene were identified. PMID: 28687848
9. Mutation in BEST1 has variable penetrance and expressivity, and can be uniocular. PMID: 27287821
10. We identified 7 BEST1 variants, 2 of which were new in 9 cases of Japanese patients with autosomal recessive bestrophinopathy. PMID: 27163236
11. Of the 225 genetic tests performed, 150 were for recessive IRD, and 75 were for dominant IRD. A positive molecular diagnosis was made in 70 (59%) of probands with recessive IRD and 19 (26%) probands with dominant IRD. Thirty-two novel variants were identified; among these, 17 sequence changes in four genes were predicted to be possibly or probably damaging including: ABCA4 (14), BEST1 (2), PRPH2 (1), and TIMP3 PMID: 28005406

14. The secondary structure of Best1 and the effect of calcium have been described. PMID: 27768912
15. BVMD could present with other ocular disorders such as ACG and FCE. We also found 2 novel disease-causing mutations (p.Thr307Asp, p.Arg47His) of the BEST1 gene, one of which (p.Arg47His) has also been reported in adult-onset vitelliform macular dystrophy (AVMD) PMID: 27078032
16. Two previously unreported disease-associated variants in the BEST1 gene (p.Gly15Arg and p.Arg105Gly) were found in Slovenian patients with Best disease. PMID: 27775230
17. Nuclear spheres modulate the expression of BEST1 and GADD45G PMID: 26521045
18. Progressive posterior chorioretinal changes occurred over time in the initial ADVIRC proband, leading to visual loss. The causative mutation in this patient falls in the transmembrane domain of the BEST1 protein, with unclear functional consequences. PMID: 26849243
19. HEK293T cells transfected with the identified BEST1 mutant showed significantly small currents compared to those transfected with the wild-type gene, whereas cells cotransfected with mutant and wild-type BEST1 showed good chloride conductance PMID: 26720466

21. We describe a novel mutation within the BEST1 gene of the heterozygous form giving rise to vitelliform lesions and secondary neovascularization successfully treated in a child with a course of bevacizumab. PMID: 25265375
22. Dysfunction of bestrophin 1 may result in abnormal ion and fluid transport by the retinal pigment epithelium (RPE) disturbing and even disrupting direct interactions between the RPE and the photoreceptors. PMID: 24328569
23. Two novel BEST1 mutations and associated clinical observations have been found in two unrelated patients with Best vitelliform macular dystrophy. PMID: 25936525

26. Best1 I366fsX18 differs from Best1 in that it lacks most of the cytosolic C-terminal domain, suggesting that the loss of this region contributes significantly to the pathogenesis of ARB in this patient. PMID: 26200502
27. Three novel BEST1 mutations are described, suggesting that many deleterious variants in BEST1 resulting in haploinsufficiency are still unknown. PMID: 25545482

31. Bestrophin-1 functions as an intracellular Cl channel which helps to accumulate and to release Ca(2+) from stores by conducting the counterion for Ca(2+). PMID: 24664688
32. Our current and past results indicate that mislocalization of Best1 is not an absolute feature of any individual bestrophinopathy. PMID: 24560797

34. Best1V1 and Best1V1Deltaex2 formed Ca2+-activated Cl-channels, showing that the N-terminus is not essential for channel function. Best1V2-expressing cells had no detectable Ca2+-activated Cl-currents, pointing to a critical role for splicing of C-terminus. PMID: 24341532
