Popis: The heavy chain variable segment gene (V(H))5 family, one of the seven immunoglobulin (Ig) V(H) families, contains two functional genes, VH251 and VH32. To investigate functional differences between these V(H)5 family genes, V(H) segments expressed by human peripheral B cells were sequenced and analyzed. One hundred fifty-three sequences with unique V(H)DJ(H) recombinations were obtained from 17 adults. The mutational frequency of VH32 derived sequences (6.4%) was higher than that of VH251 derived sequences (4.4%), resulting in a significant difference (P
