Alu sequences

Alu se·quenc·es

in the human genome a repeated, relatively conserved sequence of about 300 bp that often contains a cleavage site for the restriction enzyme AluI near the center; about 1 million copies in the human genome.

The non-coding regions are characterized by many types of repeated DNA sequences, where 10.6% consists of Alu sequences, a type of SINE (short and dispersed repeated elements) sequence and preferentially located towards the genes.

Together, the LINE and ALU sequences comprise approximately 30% of the genome (Miki 1998).
Our data also showed that the distribution of the genomic variables included in this study (genes, CpG islands, SNPs, and Alu sequences), was different for each ofthe DSCR genes; with the DSCR2 gene showing greater variation.
Alu sequences are short stretches of DNA with the unusual ability to copy themselves and jump from one chromosome to another.
PCR primers were designed toward consensus LINE-1 and Alu sequences and allowed for the amplification of a representative pool of repetitive elements to serve as a surrogate for diffuse genomic DNA methylation changes.
In view of the complexity of the premature stop codon mutations in NF1 , the existence of 7 pseudogenes and pseudogene sequences on different chromosomes, and the fact that this gene consists of 58 exons and harbors complex genomic structures, such as repetitive sequences and Alu sequences, NF1 is an ideal clinical target for evaluating the effectiveness of the SCE-NGS method for clinical applications (24,26-29).
Tens of thousands of Alu sequences lace the human genome, but their functions remain unknown.
