The structure of the human immunoglobulin heavy chain constant region (IGHC), on chromosome 14q32, comprises nine CH genes and two pseudogenes, all originating from multiple duplication events. Continuing evolution of the region is demonstrated by the finding of various types of duplicated and deleted haplotypes, which together add up to 6%. Here we provide molecular and genetic evidence that the G4 gene is duplicated in 44% of IGHC haplotypes in the Italian population. The duplication spans about 20 kb of genomic DNA and probably originated through unequal crossing over. Refined characterisation of the genomic region downstream from the G4 gene improves our knowledge of the evolutionary history of CH genes.
