Abstract To understand the architecture of the human genome, we need a complete definition of all the repeat sequence families, as these make up the majority of human DNA. We have isolated a small DNA fragment from human chromosome 21 and have used sequence analysis of this fragment to uncover a new low copy repeat element of approximately 300 bp that we term the Mermaid repeat. This repeat is related to, but is different from, the MER 12 repeat and is interspersed in the genome. Mermaid family members that we have studied are between 81%–87% identical to our preliminary consensus sequence. Therefore, we have added a new member to the large collection of human repetitive elements. In addition, we have mapped a Mermaid repeat to a telomeric position on the long arm of human chromosome 21, at 21q22.3
