Alu-mediated PCR artifacts and the constitutional t(11;22) breakpoint.
The breakpoints of the recurrent t(11;22)(q23;q11) have recently been cloned. We identified palindromic AT-rich repeats (PATRRs) on 11q23 and 22q11 as the mechanism responsible for the rearrangement. Contradictory to our results, A.S. Hill et al. (Hum. Mol. Genet., 9, 1525-1532) suggested that Alu-mediated recombination is responsible. To clarify this discrepancy, the cloned 4.5 kb der(11) junc...
متن کاملLong AT-rich palindromes and the constitutional t(11;22) breakpoint.
The constitutional t(11;22) is the most frequently occurring non-Robertsonian translocation in humans. The breakpoint (BP) of the t(11;22) has been identified within palindromic AT-rich repeats (PATRRs) on chromosomes 11 and 22, suggesting that hairpin/cruciform structures mediate double-strand breaks leading to the translocation. To further characterize the mechanism of the translocation, iden...
متن کاملAlu retrotransposition-mediated deletion.
Alu repeats contribute to genomic instability in primates via insertional and recombinational mutagenesis. Here, we report an analysis of Alu element-induced genomic instability through a novel mechanism termed retrotransposition-mediated deletion, and assess its impact on the integrity of primate genomes. For human and chimpanzee genomes, we find evidence of 33 retrotransposition-mediated dele...
متن کاملAlu element-mediated gene silencing.
The Alu elements are conserved approximately 300-nucleotide-long repeat sequences that belong to the SINE family of retrotransposons found abundantly in primate genomes. Pairs of inverted Alu repeats in RNA can form duplex structures that lead to hyperediting by the ADAR enzymes, and at least 333 human genes contain such repeats in their 3'-UTRs. Here, we show that a pair of inverted Alus place...
