108 Patients with the nonsense mutation Y2203X Three patients were identified as compound heterozygous for this nonsense mutation and the missense mutations G1961E [siblings 11a and 11b (results described above)] or R1097C (patient 12) (Figs. 3, 4). Login to comment

Scale for mfERG/perimetry shown in Fig. 1 Fig. 4 Fundus photograph, RSL, and mfERG trace arrays (from top to bottom) of patient 12 with the Y2203X mutation in one and the R1097C mutation in the second ABCA4 allele.

175 The Y2203X mutation associated with the missense mutation R1097C (NBD-1) in patient 12 resulted in a less severe phenotype than seen in patient 11a (G1961E). Login to comment
176 R1097C is located within NBD-1 but does not directly contribute to the ABC domains. Login to comment
