Non-allelic recombination between homologous repetitive elements contributes to evolution and human genetic disorders. Here, we combine short- and long-DNA read sequencing of repeat elements with a new bioinformatics pipeline to show that somatic recombination of Alu and L1 elements is widespread in the human genome.

WebSep 20, 2024 · In addition, while most somatic expansions occur via the addition of a small number of repeats with each event, contractions generally result in large and variable changes in repeat number. Furthermore, while AGG interruptions significantly reduce the intergenerational expansion frequency, they have no effect on the frequency of both … V(D)J recombination is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively. The process is a defining feature of the adaptive immune system.
