Leukocyte DNA from 9 affected and 16 unaffected members and 7 parathyroid tumors from 4 patients was used in comparative genomic hybridization (CGH), tumor loss of heterozygosity (LOH), and family linkage studies. The CGH studies revealed abnormalities of chromosomes 1 and 13, and the results of LOH studies were consistent with the involvements of tumor suppressor genes from these regions. Family segregation studies mapped HPTPort to chromosome 1q22-q31 by establishing linkage with eight loci (D1S254, D1S222, D1S202, D1S238, D1S428, D1S2877, D1S422, and D1S412) (peak two-point LOD scores = 3. 46\u20135.14 at 0% recombination), and defined the location of HPT Port to a 21 cM region flanked centromerically by D1S215 and telomerically by D1S306. Thus, HPTPort has been mapped to chromosome 1q22-q31, and a characterization of this gene will help to elucidate further the mechanisms that are involved in the development of parathyroid tumors.<\/jats:p>","DOI":"10.1359\/jbmr.1999.14.2.230","type":"journal-article","created":{"date-parts":[[2006,4,26]],"date-time":"2006-04-26T20:05:40Z","timestamp":1146081940000},"page":"230-239","source":"Crossref","is-referenced-by-count":39,"title":["Mapping the Gene Causing Hereditary Primary Hyperparathyroidism in a Portuguese Kindred to Chromosome 1q22-q31"],"prefix":"10.1093","volume":"14","author":[{"given":"C.","family":"Williamson","sequence":"first","affiliation":[{"name":"MRC Molecular Endocrinology Group, MRC Clinical Sciences Center, Imperial College School of Medicine, The Hammersmith Hospital, London, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
