While clinically dominantphenotypes, such as those caused by the p.(Gly1961Glu) mutation, aredocumented in ABCA4-associated retinopathy, thereis no reason to expect any genetically dominant cases since, basedon our current knowledge of the ABCA4 function, a dominant-negativeeffect is not expected for any ABCA4 allele. This evidence concerns the gene ABCA4 and retinal disorder.
