Complete nucleotide and amino acid sequences of monoclonal IGL gene in POEMS syndrome. (A) Complete nucleotide sequences of 2 cases (nos. 1 and 2) and previously reported 2 cases by Soubrier et al (A and B)18 with the IGLV1-40*01 germline. (B) Complete nucleotide sequences of 9 cases with the IGLV1-44*01 germline. (C) Complete amino acid sequences of these 13 cases. FR indicates framework; CDR, complementarity-determining region; hyphens represent nucleotide or amino acid identity; dots represent gaps.
