| abstractText | Four immunoglobulin heavy chain diversity (IGHD) gene subgroups (DFL16, DSP2, DQ52, and DST4) have been identified previously in BALB/c mice. Although the locations of most IGHD genes have been established based on restriction map and Southern blot analysis, a complete mouse IGHD gene locus map at the sequence level is still not available. In addition, a previous restriction fragment length polymorphism study suggested that significant difference in the IGHD gene locus exists between C57BL/6 and BALB/c mice. The author has now analyzed the C57BL/6 mouse genomic data and established a complete map of the IGHD gene locus. All four IGHD subgroups previously identified in BALB/c mice were found to be present in C57BL/6 mice. However, unlike the BALB/c mice, which have at least 13 IGHD genes, the C57BL/6 genome contains only ten IGHD genes, which include one DFL16, six DSP2, one DQ52, and two DST4 genes. There are also differences in the coding regions of the DST4 and DQ52 genes between the two mouse strains. |
