After glycine (G, WT) is replaced by arginine (R, rs1472566324), arginine forms additional hydrogen bonds with the surrounding amino acids. In the Minigene Splicing Assay, abnormal splicing bodies (associated with an Exon18 jump) were observed in the mutant plasmids (rs1416744060). This abnormal splicing event caused a deletion of 31 aa inside the protein, generating a truncated protein of 2,184 aa.\n                    <\/jats:p>\n                  <\/jats:sec>\n
