RESUMO
The 'Human Immunoglobulin Heavy Diversity (IGHD) and Joining (IGHJ) segments', fifth report of the 'IMGT Locus on Focus' section, comprises six tables entitled: (1) 'Human germline IGHD segments at 14q32.33'; (2) 'Human IGHD alleles'; (3) 'Human germline IGHJ segments at 14q32.33'; (4) 'Human IGHJ alleles'; (5) 'Human germline IGHD orphons on chromosome 15 (15q11.2)'; (6) 'Correspondence between the different human IGHD nomenclatures', and two figures: (1) 'Protein display of human IGH D-REGIONs'; (2) 'Protein display of human IGH J-REGIONs'. These tables and figures are available at the IMGT Marie-Paule page from IMGT, the international ImMunoGeneTics database (http://imgt.cnusc.fr:8104) created by Marie-Paule Lefranc, Université Montpellier II, CNRS, France.
