Description:
Two de novo insertions of truncated L1 elements into the factor VIII gene on the X chromosome have been identified that produced hemophilia A. A full-length L1 element that is the likely progenitor of one of these insertions was isolated by its sequence identity to the factor VIII insertion. This L1 element contains two open-reading frames and is one of at least four alleles of a locus on chromosome 22 that has been occupied by an L1 element for at least 6 million years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dombroski, B A -- Mathias, S L -- Nanthakumar, E -- Scott, A F -- Kazazian, H H Jr -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1805-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1662412" target="_blank"〉PubMed〈/a〉
