In 2001, Zhang et al. (1) and Edwards et al. (2) independently reported a five base pair deletion (797–801delAACT) in exon 6 of the ELOVL4 gene located on human chromosome 6q14 as the cause of early-onset macular degeneration in patients with autosomal dominant Stargardt-like macular dystrophy (STGD3). This evidence concerns the gene ELOVL4 and Stargardt disease 3.
