Fluorescence in situ hybridisation (FISH) using probes within and flanking the Prader-Willi\/Angelman syndrome critical region (PWASCR) confirmed the triplication in the abnormal 15 homologue. The inv dup(15) was dicentric, positive for IR39d which maps proximal to the PWASCR, but was negative for all the PWASCR FISH probes used. Results using polymorphic microsatellite repeats confirmed that the additional material in the trip(15) was maternal in origin and included several PWASCR loci. The presence of two de novo abnormalities involving the proximal region of 15q suggests a linked mechanism of origin.<\/jats:p>","DOI":"10.1136\/jmg.35.5.425","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T15:37:21Z","timestamp":1226331441000},"page":"425-428","source":"Crossref","is-referenced-by-count":38,"title":["Triplication of 15q11-q13 with inv dup(15) in a female with developmental delay."],"prefix":"10.1136","volume":"35","author":[{"given":"F L","family":"Long","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D P","family":"Duckett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L J","family":"Billam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D K","family":"Williams","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J A","family":"Crolla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1998,5,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1002\/ajmg.1320320235","article-title":"dromes share Latt SA.
