In a small proportion of cases, these exostoses progress to malignant chondrosarcomas. Genetic linkage of this disorder has been described to three independent loci on chromosomes 8q24.1 (EXT1), 11p11-13 (EXT2), and 19p (EXT-3). The EXT1 and EXT2 genes were isolated recently and show extensive sequence homology to each other. These genes are deleted in exostoses-derived tumors, supporting the hypothesis that they encode tumor suppressors. We have identified a third gene that shows striking sequence similarity to both EXT1 and EXT2 at the nucleotide and amino acid sequence levels, and have derived its entire coding sequence. Although the mRNA transcribed from this gene is similar in size to that from EXT1 and EXT2, its pattern of expression is quite different. We have localized this gene by fluorescence in situ hybridization to metaphase chromosomes and by whole genome radiation hybrid mapping to chromosome 1p36.1 between DIS458 and DIS511, region that frequently shows loss of heterozygosity in a variety of tumor types. This gene, EXTL (for EXT-like), is therefore a new member of the EXT gene family and is a potential candidate for several disease phenotypes.<\/jats:p>","DOI":"10.1101\/gr.7.1.10","type":"journal-article","created":{"date-parts":[[2007,6,5]],"date-time":"2007-06-05T21:18:07Z","timestamp":1181078287000},"page":"10-16","source":"Crossref","is-referenced-by-count":117,"title":["Identification and localization of the gene for EXTL, a third member of the multiple exostoses gene family."],"prefix":"10.1101","volume":"7","author":[{"given":"C A","family":"Wise","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G A","family":"Clines","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H","family":"Massa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B J","family":"Trask","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Lovett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[1997,1,1]]},"reference":[{"key":"2021111810262568000_7.1.10.1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1095-137"},{"key":"2021111810262568000_7.1.10.2","doi-asserted-by":"publisher","DOI":"10.1006\/jmbi.1990.9999"},{"key":"2021111810262568000_7.1.10.3","first-page":"734","article-title":"Delineation of a contiguous gene syndrome with multiple exostoses, enlarged parietal foramina, craniofacial dysostosis, and mental retardation, caused by deletions on the short arm of chromosome 11.","volume":"58","year":"1996","journal-title":"Am.
