156 These three alterations, in combination with five others (R681X, A1038V as noncomplex allele, R1108C, Q1412X, R1898H, and IVS40ϩ5GrA), account for 61.4% of the detectable disease chromosomes in the German patients with STGD. Login to comment
189 The findings in this study point to additional variants (2588GrC, A1038V, and R1898H) that are present in reasonable frequencies in the German population and that may be worthwhile candidates for further extended analyses in large-scale international efforts. Login to comment

142 Conclusions We reported elsewhere that seven alterations in ABCR (R1898H, G1961E, 6519del11bp, E471K, R1129L, 5196+1GA, and L1970F) are associated with STGD in compound heterozygous states and with AMD in an apparent heterozygous state (Allikmets et al., 1997a; Lewis et al., 1999). Login to comment
143 In addition, we previously showed that the most common mutant ABCR allele (G1961E) identified in a cohort of 150 families was also one of the most frequently identified disease associated ABCR alterations in a cohort of 167 AMD patients (Allikmets et al., 1997a; Lewis et al., 1999).

191 We reported previously that three AMD-associated ABCR variants (R1898H, G1961E, and 6519D11bp) (Allikmets et al. 1997a) had been identified in families with STGD1 (Allikmets et al. 1997b). Login to comment
192 Interestingly, four other STGD1-causing ABCR mutations (E471K, R1129L, 5196ϩ1GrA, and L1970F) in these new families were documented previously as AMD-associated ABCR variants (Allikmets et al. 1997a). Login to comment
