The majority of cases are caused by a benign parathyroid adenoma, but somatic or\n                    <jats:italic>de novo<\/jats:italic>\n                    germ-line mutations that lead to adenoma formation have only been identified in few glands. GCMB is a parathyroid-specific transcription factor, which causes hypoparathyroidism when inactivated on both parental alleles or when a dominant-negative, heterozygous mutation is present. It is overexpressed in some parathyroid adenomas, and we therefore tested the hypothesis that GCMB mutations can be a cause of parathyroid adenomas. Nucleotide sequence analysis was performed on all coding exons and exon\u2013intron borders of GCMB in 30 sporadic parathyroid adenomas and we identified several known polymorphisms that were either heterozygous or homozygous. In addition, one of the 30 investigated glands revealed a novel heterozygous missense mutation, c.1144G&gt;A, which introduced methionine at position 382 for valine (V382M), a conserved amino acid residue. Western blot analysis using mutant GCMB (GCMB-V382M) from lysates of transiently transfected DF-1 fibroblasts, luciferase assays using extracts from these cells, and electrophoretic mobility assays failed to reveal differences between wild-type and mutant GCMB in expression level, transactivational capacity, and DNA-binding ability. Furthermore, pulse-chase experiments demonstrated no difference in half-life of wild-type and mutant protein. We conclude that mutations in the transcription factor GCMB do not seem to play a major role in the pathogenesis of PHPT.\n                  <\/jats:p>","DOI":"10.1530\/joe-10-0247","type":"journal-article","created":{"date-parts":[[2011,6,3]],"date-time":"2011-06-03T22:22:40Z","timestamp":1307139760000},"page":"165-171","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-5","source":"Crossref","is-referenced-by-count":18,"title":["Mutational analysis of GCMB, a parathyroid-specific transcription factor, in parathyroid adenoma of primary hyperparathyroidism"],"prefix":"10.1530","volume":"210","author":[{"given":"Michael","family":"Mannstadt","sequence":"first","affiliation":[{"name":"1Endocrine Unit2Pediatric Nephrology UnitMassachusetts General Hospital and Harvard Medical School, Thier 1051, 55 Fruit Street, Boston, Massachusetts 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Holick","sequence":"additional","affiliation":[{"name":"1Endocrine Unit2Pediatric Nephrology UnitMassachusetts General Hospital and Harvard Medical School, Thier 1051, 55 Fruit Street, Boston, Massachusetts 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenping","family":"Zhao","sequence":"additional","affiliation":[{"name":"1Endocrine Unit2Pediatric Nephrology UnitMassachusetts General Hospital and Harvard Medical School, Thier 1051, 55 Fruit Street, Boston, Massachusetts 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harald","family":"J\u00fcppner","sequence":"additional","affiliation":[{"name":"1Endocrine Unit2Pediatric Nephrology UnitMassachusetts General Hospital and Harvard Medical School, Thier 1051, 55 Fruit Street, Boston, Massachusetts 02114, USA"},{"name":"1Endocrine Unit2Pediatric Nephrology UnitMassachusetts General Hospital and Harvard Medical School, Thier 1051, 55 Fruit Street, Boston, Massachusetts 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"issue":"11","key":"1_4860890","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1056\/NEJM198803173181102","volume":"318","author":"Arnold","year":"1988","journal-title":"New England Journal of Medicine","ISSN":"https:\/\/id.crossref.org\/issn\/0028-4793","issn-type":"print"},{"issue":"5","key":"2_15862597","doi-asserted-by":"crossref","first-page":"2047","DOI":"10.1172\/JCI117890","volume":"95","author":"Arnold","year":"1995","journal-title":"Journal of Clinical Investigation","ISSN":"https:\/\/id.crossref.org\/issn\/0021-9738","issn-type":"print"},{"issue":"11","key":"3_31844650","doi-asserted-by":"publisher","first-page":"1184","DOI":"10.1056\/NEJMc0802570","volume":"359","author":"Au","year":"2008","journal-title":"New England Journal of Medicine","ISSN":"https:\/\/id.crossref.org\/issn\/0028-4793","issn-type":"print"},{"issue":"5","key":"4_18839113","doi-asserted-by":"publisher","first-page":"443","DOI":"10.1136\/jmg.2004.026898","volume":"42","author":"Baumber","year":"2005","journal-title":"Journal of Medical Genetics","ISSN":"https:\/\/id.crossref.org\/issn\/0022-2593","issn-type":"print"},{"issue":"10","key":"5_36690094","doi-asserted-by":"publisher","first-page":"2028","DOI":"10.1093\/hmg\/ddq084","volume":"19","year":"2010","journal-title":"Human Molecular Genetics","ISSN":"https:\/\/id.crossref.org\/issn\/0964-6906","issn-type":"print"},{"issue":"1","key":"6_31755586","doi-asserted-by":"publisher","first-page":"85","DOI":"10.1002\/humu.20827","volume":"30","author":"Canaff","year":"2009","journal-title":"Human mutation","ISSN":"https:\/\/id.crossref.org\/issn\/1059-7794","issn-type":"print"},{"issue":"4","key":"7_17260713","doi-asserted-by":"publisher","first-page":"501","DOI":"10.1046\/j.1365-2265.2002.01627.x","volume":"57","author":"Correa","year":"2002","journal-title":"Clinical endocrinology","ISSN":"https:\/\/id.crossref.org\/issn\/0300-0664","issn-type":"print"},{"issue":"4","key":"8_23607395","doi-asserted-by":"publisher","first-page":"1564","DOI":"10.1210\/jc.2006-2554","volume":"92","year":"2007","journal-title":"Journal of Clinical Endocrinology &amp;
