Topics Covered

• Rearrangements of the human genome as a significant source for genetic variation
• Genomic disorders
• Inherited and sporadic traits
• Rearrangements associated with genomic disorders can be recurrent, with breakpoint clusters resulting in a common sized deletion/duplication, or nonrecurrent and of different sizes
• Nonallelic homologous recombination (NAHR)
• Nonhomologous end-joining (NHEJ)
• Low-copy repeats (LCRs)
• Fork Stalling and Template Switching (FoSTeS)
• Rearrangements as an evolutionary function
• Gene dosage, position effects, unmasking of coding region mutations (cSNPs) and other functional SNPs
• De novo genomic rearrangements have been shown to cause both chromosomal and Mendelian disease, as well as sporadic traits
• Understanding of the extent to which genomic rearrangements, gene CNV, and/or gene dosage alterations are responsible for common and complex traits remains rudimentary
