94 Performing DHPLC and sequence analysis we also detected four different ABCC6 mutations (c.1995delG, p.R765Q, c.2787+1G>T, and p.L946I) which had already been categorized as PXE-causing mutations by other groups (Table 2) [9, 19, 20, 22]. Login to comment
97 Seven healthy control individuals were heterozygous for the missense mutation p.L946I, which was novel at the time of investigation. Login to comment
131 Morcher et al. [22] considered the missense mutation p.L946I causative for a manifestation of PXE. This observation is not in accordance with the data that we obtained from a control cohort of 100 healthy Westphalian blood donors to investigate the role of p.L946I in PXE. Login to comment
132 The appearance of p.L946I in the general population sheds doubt on the view that p.L946I is a disease-causing mutation but rather a polymorphism. Login to comment
133 However, we cannot rule out the possibility that p.L946I has a phenotypic effect in a compound heterozygote with a severe mutation on the other allele. Login to comment

199 Coding sequence SNPs were considered as neutral (non-disease-causing) when they resulted in a synonymous amino acid substitution or a nonsynonymous substitution that did not cosegregate with the disease haplotype and phenotype (p.V614A, p.R724K, p.I742V, p.L946I, p.R1064W, and p.R1268Q) or did cosegregate with other PXE mutations in linkage disequilibrium in individual families (p.V514I, p.H632Q, and p.R1268Q).

100 Three rare missense variants, A78T, L726P and L946I, were each identified once and were characterised. Login to comment
105 Two of these, L726P and L946I, were present in a single white bilingual South African patient (PXE2), the father was a carrier of L726P and the mother of L946I, confirming that they were inherited as independent alleles. Login to comment
111 L946I is a conservative amino acid change from leucine (L) to isoleucine (I) (both amino acids are non-polar, neutral and hydrophobic) in the transmembrane domain (TMD) of ABCC6. Login to comment
