Genomic Rearrangements and Evolution

Large genomic rearrangements in MECP2.

In 1999, mutations in the X-linked gene methyl-CpG-binding protein 2 (MECP2) were first reported in patients with Rett syndrome (RTT). The MECP2 gene is located at Xq28 and consists of 4 exons. About 80-90 % of the classic RTT patients harbor mutations in the coding region of MECP2, while the molecular cause is unknown in the remaining 10-20%. Several groups have searched for large rearrangemen...

Mitochondrial genomic rearrangements in songbirds.

The organization of the mitochondrial genome is generally very conserved among vertebrates. Because of this, examination of the rare rearrangements which do occur has been suggested as offering a powerful alternative to phylogenetic analyses of mitochondrial DNA sequences. Here, we report on an avian mitochondrial rearrangement in a group of oscine passerines (warblers of the genus Phylloscopus...

Genomic rearrangements in inherited disease and cancer.

Genomic rearrangements in inherited disease and cancer involve gross alterations of chromosomes or large chromosomal regions and can take the form of deletions, duplications, insertions, inversions or translocations. The characterization of a considerable number of rearrangement breakpoints has now been accomplished at the nucleotide sequence level, thereby providing an invaluable resource for ...

Mechanisms for human genomic rearrangements

Genomic rearrangements describe gross DNA changes of the size ranging from a couple of hundred base pairs, the size of an average exon, to megabases (Mb). When greater than 3 to 5 Mb, such changes are usually visible microscopically by chromosome studies. Human diseases that result from genomic rearrangements have been called genomic disorders. Three major mechanisms have been proposed for geno...
