MFSD8 and Macular dystrophy: Up to now, isolated maculopathies were found to be associated with over 26 genes and 2 loci, of which ATP binding cassette subfamily A member 4 gene (ABCA4) is the most frequently involved and the Major Facilitator Superfamily Domain containing Protein‐8 gene (MFSD8, encoding CLN7) one of the more recently identified genes.1, 2, 3, 4 The associated phenotype of the latter is characterized by macular dystrophy with central cone involvement or widespread retinopathy.
