Familial multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant disorder characterized by the combined occurrence of tumors of the parathyroid glands, the endocrine pancreas, and the pituitary gland. MEN 1 tumors have previously been shown to be associated with the loss of alleles on chromosome 11, and deletion mapping studies together with family linkage studies have localized the MEN 1 gene to 11q13. A detailed genetic map around the MEN 1 locus is required to facilitate further characterization and cloning of the gene (MEN1). We have characterized a panel of seven rodent-human somatic cell hybrids which contain fragments of human chromosome 11 with breakpoints in the pericentromeric region by using eight DNA sequences (D11S149, PGA, PYGM, D11S97, INT2, D11S37, D11S533, and D11S147) to define the region containing MEN1. This will facilitate the rapid localization of additional DNA sequences in this region. In addition, we have used a highly polymorphic repetitive degenerate hexanucleotide sequence, designated D11S533, for segregation studies in one family with MEN 1. These molecular genetic approaches will help to define a precise 1 to 2 centiMorgan map around MEN1.

Multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant disorder that predisposes affected individuals to neoplasms of the parathyroid glands, endocrine pancreas, anterior pituitary, and carcinoids. The MEN1 locus has been localized by family studies to 11q13, flanked by markers PGA and D11S97. Eight new polymorphisms located in three separate radiation-reduced somatic cell hybrid segregation groups were developed. The order of the new markers, within the context of previously described loci, was determined by linkage analysis on the Venezuelan reference pedigree. Four independent MEN1 families, consisting of 57 affected individuals, and 70 individuals at-risk for the disease were genotyped. Sixteen people inherited a chromosome that shows recombination between a linked marker and the disease. The nearest proximal and distal markers that show recombination with the disease are D11S822 and GSTP1, respectively, thereby narrowing the candidate region for MEN1 by 50% on the distal side. Using these loci in haplotype analysis, an accurate presymptomatic molecular diagnostic test has been developed. These new markers in 11q13 linked to MEN1 also facilitate the genetic and physical characterization of this very gene-rich region.

We report a pulsed-field gel electrophoresis map of 12 loci on proximal human chromosome 11q. Linkage studies have shown that this region of chromosome 11 contains the genes for familial atopic disease (APY) and multiple endocrine neoplasia type I (MEN1) (4). A physical map containing polymorphic loci will aid in the isolation of these disease genes. The map reported here has two noncontiguous groups of loci accounting for 8 of the 12 loci evaluated. One group spans a maximum distance of 1600 kb and includes D11S146, BCL1, PRAD1, INT2, and HSTF1. The other group includes FTH1, C1NH, and COX8. TCN1, PGA, and PYGM did not yield any comigrating fragments and could not be physically linked on this PFGE map. These data enhance previously published physical maps of proximal 11q by refining the localization of and distances between markers in the BCL1 region. Additionally, new information about the locations and physical relationships between FTH1, C1NH, and COX8 is presented.
