153 The milder phenotype in her mother (patient 1b), who was shown to be compound heterozygous for the 5917delG and G1961E mutation, is not unexpected since the G1961E mutation in her second allele is thought to result in partial activity of the ABCA4 transporter [49]. Login to comment
154 The combination of the IVS40+5G→A splice site mutation and the C1488Y missense (patient 2) or the Y362X nonsense (patient 3) mutation resulted in an early age at onset but only a central cone and rod dysfunction at age 15 and 13. Login to comment
158 The slightly more advanced cone dysfunction in patient 3 could be caused by the more severe functional restrictions of the associated nonsense mutation (Y362X), which results in a non-functional gene product. Login to comment
