153 example, among the 14 patients compound heterozygous for the common G1961E allele (Supplementary Table S1), the model would predict foveal disease in the first decade of life for three alleles (P68L;G1961E, L541P;A1038V, and T1019M), second decade of life for four alleles (R1129L, C54Y, R152Stop, and V256V) and fourth decade of life for four alleles (P1380L, R1640Q, c.5312&#fe;1 G>A, and M669fs).
