8 Six variants were successfully identified as causal mutations for AS (p.R419Q, p.E422K, c.2542delG, Del_Exon23, c.3774-3775insC and p.E1427K), and 4 of these were novel. Login to comment
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. The homozygous Del_Exon23 was found in 2 subjects with the homozygous GTGA/GTGA diplotype. Login to comment

Nonsynonymous variants were shown by the amino acid numbers started by the strat codon methionine. The cDNA base numbers refer to the nucleotide in the cDNA, where nucleotide 1 is the A of the first ATG.

119 The most common alleles were c.2542delG (25.0%), p.R419Q (13.9%), Del_Exon23 (3.7%), followed by c.3774-3775insC, p.E422K, p.S587C, p.A950V and p.E1427K (all 0.93%). Login to comment
120 With regard to genotyping for each subject, 7 patients had c.2542delG/c.2542delG, 6 had p.R419Q/p.R419Q, 2 had Del_Exon23/Del_Exon23, 1 had c.2542delG/c.3774-3775insC and 1 had p.E422K/c.2542delG. Login to comment
121 There were 17 patients with only 1 allele, 11 patients with c.2542delG/À, 3 with p.R419Q/À, 1 with p.S587C/À, 1 with p.A950V/À and 1 with p.E1427K/À. Login to comment
135 The 3 most frequent alleles, c.2542delG (27 alleles), p.R419Q (15 alleles) and Del_Exon23 (4 alleles), accounted for more than 90%. Login to comment
137 Of 15 p.R419Q alleles, 14 alleles were linked to the GTGG haplotype (14/15 = 93.3%), of 27 c.2542delG alleles, 24 alleles were linked to the ATGA haplotype (24/27 = 88.9%) and of 4 Del_Exon23 alleles, 4 alleles were linked to the GTGA haplotype (4/4 = 100%). Login to comment
