Chromosome 11 ideogram showing the approximate positions of genes implicated in various retinal phenotypes, mapped according to their distance from the 11p telomere. Distances are composites derived from the databases of Retnet, OMIM, and the Centre for Medical Genetics, Marshfield Medical Research Foundation. AA = locus for atrophia areata; BBS1 = locus for Bardet-Biedl syndrome locus; EVR1 = locus for autosomal dominant familial exudative vitreoretinopathy locus; EVR3 = locus for the new locus described in the present article; MYO7A = locus for Usher syndrome 1B; ROM1 = gene involved in digenic and, possibly, in dominant retinitis pigmentosa; USH1C = locus for Usher syndrome 1C; and VNR1 = locus for autosomal dominant inflammatory vitreoretinopathy.
