We have deduced the sequence of a composite long interspersed repeated DNA in primates and herein describe its relationship to a complex repeat element (L1Heg) located in the interval linking the human epsilon- and G gamma-globin genes. The main element of L1Heg is 3' truncated and interrupted by the insertion of the 3' end of a second L1 element. Transposition of L1Heg into this intergenic locus generated a 62-bp duplication of flanking sequences. In contrast, insertion of the second repeat may have been mediated by homology between donor and target sequences. The main repeat represents a novel class of abundant elements whose sequences have diverged from other rodent and primate LINES approximately 1.3 kb downstream from the 5' terminus of L1Heg. Comparison of L1Heg with the sequences of two other related L1 members revealed a complex set of rearrangements confined within a region that resembles the long terminal repeats of other types of retroposons. The boundaries of conversion-like events were defined on the basis of the clustering of nucleotide sequence variants common to two or more nonallelic 3' L1H elements. Several of these events are apparently initiated or resolved within a common 150-bp region that coincides with the 3' terminus of a pan-mammalian open reading frame. This analysis showed that concerted genetic interactions and random drift both contribute appreciably to sequence variation within this set of L1H members.
