  4. 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.

  5. 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.

  6. We describe a highly recognizable and reproducible retinal phenotype associated with a specific BEST1 mutation-p.Ala243Val in vitelliform macular dystrophy.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

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

  14. We describe the atypical phenotype and high intrafamilial variability associated with a new mutation in the BEST1 gene in an Italian family affected with Best vitelliform macular dystrophy.

  16. The secondary structure of Best1 and the effect of calcium have been described.

  17. 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)

  18. Two previously unreported disease-associated variants in the BEST1 gene (p.Gly15Arg and p.Arg105Gly) were found in Slovenian patients with Best disease.

  19. Nuclear spheres modulate the expression of BEST1 and GADD45G

  20. 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.

  1. 14-3-3gamma promotes surface expression of Best1 channel in astrocytes through direct interaction.

  2. Data suggest that the ion channels CaV1.3, bestrophin-1 and maxiK were identified as players in the regulation of photoreceptor outer segments (POS) phagocytosis by the retinal pigment epithelium (RPE).

  3. Best1-mediated astrocytic glutamate activates the synaptic N-methyl-D-aspartate receptor (NMDAR) and modulates NMDAR-dependent synaptic plasticity.

  4. 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+).

  5. Best1, located at the microdomains near the synaptic junctions, has a significantly high permeability to glutamate in vivo.

  6. Results show that different mutations in Best1 cause differential effects on its localization and that this effect varies with the presence or absence of wild-type (WT) Best1.

  7. Astrocytic glutamate via Best1 channel targets and activates synaptic NMDA receptors.

  8. Upon activation of protease activated receptor 1 (PAR1), an increase in intracellular Ca2+ concentration leads to an opening of Best1 channels and subsequent release of glutamate in cultured astrocytes.

  9. Ultrastructural analyses demonstrate that TREK-1 is preferentially localized at cell body and processes, whereas Best1 is mostly found in microdomains of astrocytes near synapses.

  10. study reports that tonic inhibition in the cerebellum is due to GABA being released from glial cells by permeation through the Bestrophin 1 anion channel

  13. Data demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it interacts with the ER-Ca(2+) sensor and can enhance Ca(2+) signaling and activation of Ca(2+)-dependent Cl(-) (TMEM16A) and K(+) (SK4) channels.

  14. cloning and characterization by combining biocomputational analyses and molecular genetic approaches

  15. We suggest the loss of vision associated with Best vitelliform macular dystrophy is not caused by the same pathologic process as the diminished light peak, but is caused by an unidentified effect of best-1 [VMD2] on other cellular processes.

  16. BEST1 may form the Ca2+-activated Cl(-) current, or it may be a component of a Cl(-) channel complex in epithelial tissues.

  17. VMD2 is regulated by the MITF-TFE family through two E-boxes, with E-box 1 required for a direct interaction of MITF-TFE factors and E-box 2 for binding of the as yet unidentified factors

Bestrophin 1 (BEST1) Antigen Profile

Protein Summary

This gene encodes a member of the bestrophin gene family. This small gene family is characterized by proteins with a highly conserved N-terminus with four to six transmembrane domains. Bestrophins may form chloride ion channels or may regulate voltage-gated L-type calcium-ion channels. Bestrophins are generally believed to form calcium-activated chloride-ion channels in epithelial cells but they have also been shown to be highly permeable to bicarbonate ion transport in retinal tissue. Mutations in this gene are responsible for juvenile-onset vitelliform macular dystrophy (VMD2), also known as Best macular dystrophy, in addition to adult-onset vitelliform macular dystrophy (AVMD) and other retinopathies. Alternative splicing results in multiple variants encoding distinct isoforms.
