They arise sporadically or occur secondary to inherited cancer syndromes, such as multiple endocrine neoplasia type II (MEN2), von Hippel\u2010Lindau disease (VHL), or neurofibromatosis type I (NF1). Loss of 1p is the most frequently encountered genetic alteration, especially in MEN2\u2010related and sporadic PCC. Previous studies have revealed three regions of common somatic loss on chromosome arm 1p, using chromosome\u2010based comparative genomic hybridization (CGH) and LOH analysis. To investigate these chromosomal aberrations with a higher resolution and sensitivity, we performed microarray\u2010based CGH with 13 sporadic and 11 syndrome\u2010related (10 MEN2A\u2010related and 1 NF1\u2010related) tumors. The array consisted of 642 overlapping bacterial artificial chromosome (BAC) clones mapped to 1p11.2\u2010p36.33. Chromosomal deletions on 1p were detected in 18 of 24 cases (75%). Among 9 tumors with partial 1p loss, the deleted region was restricted to 1cen\u20101p32.3 in six cases (25%), indicating a region of genetic instability. The consensus regions of deletion in this study involved 1cen\u20101p21.1, 1p21.3\u20101p31.3, and 1p34.3\u20101p36.33. In conclusion, these data strongly suggest that chromosome arm 1p is the site for multiple tumor suppressor genes, although the potential candidate genes <jats:italic>CDKN2C<\/jats:italic> and <jats:italic>PTPRF\/LAR<\/jats:italic> are not included in these regions. \u00a9 2005 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/gcc.20268","type":"journal-article","created":{"date-parts":[[2005,10,7]],"date-time":"2005-10-07T16:17:33Z","timestamp":1128701853000},"page":"83-93","source":"Crossref","is-referenced-by-count":30,"title":["Microarray\u2010based CGH of sporadic and syndrome\u2010related pheochromocytomas using a 0.1\u20130.2 Mb bacterial artificial chromosome array spanning chromosome arm 1p"],"prefix":"10.1002","volume":"45","author":[{"given":"Marieke","family":"Aarts","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hilde","family":"Dannenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald J.","family":"deLeeuw","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francien H.","family":"van Nederveen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert A.","family":"Verhofstad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
