Cross-species summary: See also BEST1-related multifactorial retinopathy in dogs: OMIA:001444-9615: Multifocal retinopathy 1 in Canis lupus familiaris (dog), OMIA:001553-9615: Multifocal retinopathy 2 in Canis lupus familiaris (dog), OMIA:001554-9615: Multifocal retinopathy 3 in Canis lupus familiaris (dog).

Molecular basis: Yi et al. (2025) "report a Macaca fascicularis carrying a heterozygous potential pathogenic BEST1p.Q327E variant that disrupts the BEST1 ion channel by destabilizing the A195 helix, mirroring the structural perturbations seen in certain human pathological mutants."

Clinical features: Yi et al. (2025): "Longitudinal imaging over 2 years revealed progressive macular changes, including subfoveal cleft enlargement, lipid-rich deposit accumulation, retinal pigment epithelium (RPE) disruption, and central-to-peripheral photoreceptor degeneration ... ."

Pathology: Yi et al. (2025): "Histopathology demonstrated diminished BEST1 expression, attenuation of the RPE-photoreceptor interface, and 2 distinct types of lipid deposits, including heretofore unappreciated cone mitochondrial-enriched lesions, highlighting selective cone mitochondria vulnerability."

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
