The bestrophinopathies are a group of inherited retinal dystrophies due to mutations in BEST1 and characterised by reduced vision and an early and significant reduction in the electro-oculogram (EOG) light rise. Diseases attributable to BEST1 mutations include Best disease or vitelliform macular dystrophy (VMD) and autosomal recessive bestrophinopathy (ARB).
Mutation screening of the BEST1 gene is available for affected individuals. Pre-symptomatic, carrier testing and prenatal diagnosis are available in families with a previously identified mutation. Confirmation of mutations identified in research laboratories.
