Chromosomal stabilisation by a subtelomeric rearrangement involving two closely related Alu elements.
We have characterised a subtelomeric rearrangement involving the short arm of chromosome 16 that gives rise to alpha-thalassaemia by deleting the major, remote regulatory element controlling alpha-globin expression. The chromosomal breakpoint lies in an Alu family repeat located only approximately 1...

description | We have characterised a subtelomeric rearrangement involving the short arm of chromosome 16 that gives rise to alpha-thalassaemia by deleting the major, remote regulatory element controlling alpha-globin expression. The chromosomal breakpoint lies in an Alu family repeat located only approximately 105 kb from the 16p subtelomeric region. The broken chromosome has been stabilised with a newly positioned telomere acquired by recombination between this 16p Alu element and a closely related subtelomeric Alu element of the Sx subfamily. It seems most likely that this abnormal chromosome has been rescued by the mechanism of telomere capture which may reflect a more general process by which subtelomeric sequences are normally dispersed between chromosomal ends. |
