Involvement in diseaseDefects in BEST1 are the cause of vitelliform macular dystrophy type 2 (VMD2) [MIM:153700]; also known as Best macular dystrophy (BMD). VMD2 is an autosomal dominant form of macular degeneration that usually begins in childhood or adolescence. VMD2 is characterized by typical 'egg-yolk' macular lesions due to abnormal accumulation of lipofuscin within and beneath the retinal pigment epithelium cells. Progression of the disease leads to destruction of the retinal pigment epithelium and vision loss.
Defects in BEST1 are the cause of retinitis pigmentosa type 50 (RP50) [MIM:613194]. A retinal dystrophy belonging to the group of pigmentary retinopathies. RP is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.
Defects in BEST1 are a cause of adult-onset vitelliform macular dystrophy (AVMD) [MIM:608161]. AVMD is a rare autosomal dominant disorder with incomplete penetrance and highly variable expression. Patients usually become symptomatic in the fourth or fifth decade of life with a protracted disease of decreased visual acuity.
Defects in BEST1 are the cause of bestrophinopathy autosomal recessive (ARB) [MIM:611809]. A retinopathy characterized by central visual loss, an absent electro-oculogram light rise, and a reduced electroretinogram.
Defects in BEST1 are the cause of vitreoretinochoroidopathy autosomal dominant (ADVIRC) [MIM:193220]. A disorder characterized by vitreoretinochoroidal dystrophy. The clinical presentation is variable and may be associated with cataract, nanophthalmos, microcornea, shallow anterior chamber, and glaucoma.

ab2182 staining pig retinal pigment epithelium tissue sections. The tissue was fixed with paraformaldehyde, permeabilized in 0.5% TX100, 5% goat serum, 1XPBS, and blocked with 5% serum for 20 minutes at 25°C. The primary antibody was diluted 1/500 in 1% goat serum, 0.1% TX100, 1XPBS and incubated for 12 hours at 4°C. An Alexa Fluor® 488 conjugated goat anti-mouse was used as the secondary antibody.
The image shows bestrophin, which localises to the retinal pigment epithelial (RPE) cells, labeled with green fluorescence. Nuclei were counterstained with DAPI (blue).
Anti-Bestrophin antibody [E6-6] (ab2182) at 1/1000 dilution + Human RPE cell lysate
ab2182 staining cells of bovine retinal pigment epithelium (RPE) by ICC/IF. Cells were PFA fixed and permeabilized in 0.5% Triton X-100 prior to blocking in 10% goat serum for 20 minutes at 25°C. The primary antibody was diluted 1/500 and incubated with the sample for 12 hours at 4°C. An Alexa Fluor® 546 conjugated goat anti-mouse antibody was used as the secondary. Image A shows bestrophin localized in the basolateral side of the RPE cells labeled with red fluorescence (nuclei were counterstained with DAPI (blue)). Image B, a phase contrast (DIC) image, shows cellular structure.
