156 Most of the neutral variants were unique; however, two of these alleles (V614A and R1268Q) were found at 81.9% and 9.4%, respectively, in the cohort of patients with PXE. Login to comment

92 Six other variants (G61D, K281E, I319V, V614A, H632Q and R1268Q) resulted in amino acid changes but appeared not to segregate with the disease in PXE pedigrees and were therefore likely to be neutral. 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).

84 We identified 8 nonsynonymous variants and a deletion variant in the exon regions; p.R419Q (Exon10), p.S587C (exon13), p.V614A (Exon14), p.H632Q (Exon15), c.2542delG (Exon19), p.A950V (Exon22), p.R1268Q (Exon27) and p.E1427K (Exon30). Login to comment
104 Disease-causing mutations The homozygous p.R419Q and the homozygous p.R1268Q were found in 2 subjects with the homozygous GTGG/GTGG diplotype. The homozygous c.2542delG and the homozygous p.H632Q or homozygous p.V614A were found in each subject with the homozygous ATGA/ATGA diplotype.

110 Of the 9 variants, p.V614A, p.H632Q and p.R1268Q were previously reported as non-causal variants for PXE. Although c.2542delG (Exon19) was seen in the control group, this is defined as the disease-causing mutation because it yields a premature stop codon. Login to comment
