Birt-Hogg-Dube syndrome (BHD) is an autosomal dominant neoplasia syndrome characterized mainly by benign skin tumors, and to a lesser extent, renal tumors and spontaneous pneumothorax. To map the BHD locus, we performed a genome-wide linkage analysis using polymorphic microsatellite markers on a large Swedish BHD family. Evidence of linkage was identi®ed on chromosome 17p12-q11.2, with a maximum LOD score of 3.58 for marker D17S1852. Further haplotype analysis de®ned a *35 cM candidate interval between the two¯anking markers, D17S1791 and D17S798. This information will facilitate the identi®cation of the BHD gene, leading to the understanding of its underlying molecular etiology. Oncogene (2001) 20, 5239 ± 5242.
