Human subtelomeric segmental duplications ('subtelomeric repeats') comprise about 25% of the most distal 500 kb and 80% of the most distal 100 kb in human DNA. A systematic analysis of the duplication substructure of human subtelomeric regions was done in order to develop a detailed understanding of subtelomeric sequence organization and a nucleotide sequence-level characterization of subtelomeric duplicon families.

Software tool that screens DNA sequences for interspersed repeats and low complexity DNA sequences. The output of the program is a detailed annotation of the repeats that are present in the query sequence as well as a modified version of the query sequence in which all the annotated repeats have been masked (default: replaced by Ns). Currently over 56% of human genomic sequence is identified and masked by the program. Sequence comparisons in RepeatMasker are performed by one of several popular search engines including nhmmer, cross_match, ABBlast/WUBlast, RMBlast and Decypher. RepeatMasker makes use of curated libraries of repeats and currently supports Dfam ( profile HMM library ) and RepBase ( consensus sequence library ).
