Sublocalization Of The Multiple Endocrine Neoplasia Type 1 Gene, Catharina Larsson, Gunther Weber, Marie Janson
Sublocalization Of The Multiple Endocrine Neoplasia Type 1 Gene, Catharina Larsson, Gunther Weber, Marie Janson
Henry Ford Hospital Medical Journal
Tumorigenesis in multiple endocrine neoplasia type 1 (MEN 1) involves the unmasking of a recessive mutation at the MEN 1 locus which has been mapped to chromosomal region 11q11-13. By analyzing 58 DNA markers on a panel of radiation-reduced somatic cell hybrids, the region encompassing the MEN 1 gene was divided into nine subregions. Pulsed field gel electrophoresis analysis of markers within subgroups showed that the recombination rate around the MEN 1 locus is high. Combined linkage analysis in MEN 1 families and deletion mapping in MEN 1-related tumors suggest the MEN 1 gene is located centromeric to D11S807 and …

Prospective Screening In Multiple Endocrine Neoplasia Type 1, Britt Skogseid, Kjell Oberg
Henry Ford Hospital Medical Journal
To assess the age of clinically detectable onset of multiple endocrine neoplasia type 1 (MEN 1), 88 members of four families were invited to participate in a ten-year biochemical screening program. Evidence for clinically detectable MEN 1 was found in adolescence. Pancreatic endocrine dysfunction constituted the presenting lesion in a majority of these individuals. The age at diagnosis of pancreatic endocrine tumors averaged 25 years and was lowered by almost two decades by prospective investigation. Furthermore, the penetrance of the pancreatic endocrine and parathyroid lesions equaled the penetrance found in autopsy studies. The use of a standardized meal stimulation test …

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 …
Practical Guidelines For Dna-Based Testing In Multiple Endocrine Neoplasia Type 1, Catharina Larsson, Magnus Nordenskjold, Britt Skogseid, Kjell Oberg
Practical Guidelines For Dna-Based Testing In Multiple Endocrine Neoplasia Type 1, Catharina Larsson, Magnus Nordenskjold, Britt Skogseid, Kjell Oberg
Henry Ford Hospital Medical Journal
Multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant predisposition to neoplastic lesions of the parathyroid glands, the neuroendocrine pancreas, and the anterior pituitary gland. The predisposing genetic defect was localized to the long arm of chromosome 11 by genetic linkage analysis in three affected families. By analyzing six MEN 1 families with 14 DNA marker systems located close to the MEN 1 gene, we have developed a method to identify carriers of the MEN 1 predisposition. We describe practical aspects of such DNA-based diagnostic procedures.

Henry Ford Hospital Medical Journal
Hyperparathyroidism is a central component of multiple endocrine neoplasia type 1 (MEN 1), and both sporadic and familial forms of parathyroid disease may share certain pathogenetic features. We recently identified a gene that is clonally rearranged with the PTH locus in a subset of sporadic parathyroid adenomas. This candidate oncogene, PRAD1 (previously D11S287), appears to contribute to parathyroid tumorigenesis in a fashion analogous to activation of C-MYC or BCL-2 by rearrangement with tissue-specific enhancers of the immunoglobulin genes in B-lymphoid neoplasia. The PRAD1 gene maps to 11q13 and has been linked to the BCL-1 breakpoint locus, although not to the …

Hyperparathyroidism With Normal Albumin-Corrected Total Calcium In Patients With Multiple Endocrine Neoplasia Type 1, J. J. Shepherd, Bin Tean Teh, V. Parameswaran, R. David
Henry Ford Hospital Medical Journal
In the largest reported family of patients with multiple endocrine neoplasia type 1 (MEN 1), hyperparathyroidism was expressed at first screening in 33 patients by elevation of ionized calcium (IC) (30 cases) or parathyroid hormone (three cases) without elevation of albumin-corrected total calcium (ACTC). Three of these 33 patients have shown a progressive rise in IC and later an elevation of ACTC. However, the age distribution suggests that in others the level of IC may remain stable at a minimally elevated level throughout life with ACTC remaining normal except for transient rises at the times of intercurrent illness or surgical …

Primary Hyperparathyroidism In Patients With Multiple Endocrine Neoplasia Type 1: Experience By A Single Surgical Team In Japan, Takao Obara, Yoshihide Fujimoto, Yukio Ito
Henry Ford Hospital Medical Journal
Nineteen patients were surgically treated for hyperparathyroidism associated with multiple endocrine neoplasia type 1 syndrome. Fourteen patients (74%) had removal of three or more parathyroid glands at the first operation, and five (26%) by removal of 2 1/2 or fewer glands. Two patients had recurrent hypercalcemia during the mean follow-up period of 65 months. One had a recurrence 10 years after subtotal parathyroidectomy. Reexploration in this patient revealed enlargement of the remaining tissue in the neck and an enlarged supernumerary gland in the aorticopulmonary window. The other patient had persistent hypercalcemia after removal of two hyperplastic parathyroid glands until after …
Parathyroid Tumor Biology In Familial Multiple Endocrine Neoplasia Type 1: A Model For Cancer Development, Maria Luisa Brandi
Parathyroid Tumor Biology In Familial Multiple Endocrine Neoplasia Type 1: A Model For Cancer Development, Maria Luisa Brandi
Henry Ford Hospital Medical Journal
Familial multiple endocrine neoplasia type 1 (FMEN 1) is an autosomal dominant disorder characterized by tumors of the parathyroid glands, pancreatic islets, and anterior pituitary. Hyperplasia appears to be the typical histopathological lesion in FMEN 1 endocrine tumors. A circulating mitogen related to basic fibroblast growth factor was active on proliferation of clonal bovine and human parathyroid endothelial cells. Moreover, the FMEN 1 mitogen modulated differentiation of human parathyroid endothelial cell in vitro. All these facts suggested that an extrinsic factor was active on parathyroid endothelial cell growth and differentiation. The FMEN 1 gene maps to chromosome 11q13, and allelic …
Surgical Treatment Of The Endocrine Pancreas And Zollinger-Ellison Syndrome In The Men 1 Syndrome, Norman W. Thompson
Surgical Treatment Of The Endocrine Pancreas And Zollinger-Ellison Syndrome In The Men 1 Syndrome, Norman W. Thompson
Henry Ford Hospital Medical Journal
Islet cell neoplasia is a frequent occurrence in multiple endocrine neoplasia type 1 (MEN 1). Sixteen of 27 patients with MEN 1 developed functioning endocrine pancreatic tumor syndromes. Eleven of the 16 developed Zollinger-Ellison syndrome and each was evaluated by a combination of computed tomography and hepatic angiography to exclude hepatic metastasis and percutaneous transhepatic catheterization to localize the tumor. Seven of the 11 patients were found to have duodenal gastrinomas with multiple duodenal tumors in three patients. Four of the 11 patients had only pancreatic gastrinomas. In addition to the gastrinomas, other types of islet tumors in the pancreatic …
Isolation Of Yac Clones From The Pericentromeric Region Of Chromosome 10 And Development Of New Genetic Markers Linked To The Multiple Endocrine Neoplasia Type 2a Gene, Terry C. Lairmore, James R. Howe, Shenshen Dou, Rosalie Veile, Jennifer A. Korte-Sarfaty, Samuel A. Wells Jr., Helen Donis-Keller

Henry Ford Hospital Medical Journal
Genetic linkage mapping and contig assembly using yeast artificial chromosome (YAC) technology form the basis of our strategy to clone and define the genomic structure of the pericentromeric region of chromosome 10 containing the multiple endocrine neoplasia type 2A gene. Thus far YAC walks have been initiated from five chromosome 10 pericentromeric loci including RBP3, D10S94, RET, D10Z1, and FNRB. Long range pulsed-field gel electrophoresis maps are constructed from the YACs isolated to define clone overlaps and to identify putative CpG islands. Bidirectional YAC walks are continued by rescreening the YAC library with sequence-tagged site assays developed from endclones. Several …

We have analyzed DNA marker typing data contributed by six independent groups to estimate the pairwise genetic distances between these markers and the locus for multiple endocrine neoplasia type 2A (MEN 2A). We used LIPED to calculate these distances for female, male, and sex-average linkage maps and to determine the corresponding LOD scores. The preliminary analyses of this large data set (89 MEN 2A families and five non-MEN 2A references families, with 1,934 total individuals) are reported here. These refined estimates of the genetic map in this region will aid in the assignment of presymptomatic diagnoses. This study clearly points …

Henry Ford Hospital Medical Journal
We studied the expression of the ret proto-oncogene (proto-ret) in human medullary thyroid carcinomas (MTCs) and pheochromocytomas of multiple endocrine neoplasia type 2A (MEN 2A) by Northern blot analysis. Expression of the normal-sized transcripts was detected in all 12 MTCs and in 6 of 8 pheochromocytomas. In situ localization of proto-ret mRNA revealed that the signal was confined to the cytoplasm of MTC cells. By Southern blot analysis neither amplification nor gross genetic changes of proto-ret were found in the tumors. Although no transcripts were detected in the normal portion of the thyroid from one MEN 2A patient,faint signals were …

Henry Ford Hospital Medical Journal
The search for the gene that causes the multiple endocrine neoplasia type 2A (MEN 2A) syndrome is entering a new phase. Genetic linkage studies have localized the gene to the pericentromeric region of chromosome 10. The statistical portion of mapping the gene for MEN 2A is nearly complete and now classical molecular biological/gene mapping techniques will be employed. We have used fluorescence in situ hybridization to estimate the size of the MEN2A region to be about 2 to 5 mb, using some liberal assumptions; at worst the region should contain no more than about 10 mb of non-alphoid DNA. Our …

Nine chromosome 10 DNA markers (FNRB, D10S34, D10Z1, MEN203, D10S94, RBP3, D10S15, MBP [48.11], D10S22) were typed in two large Canadian pedigrees with multiple endocrine neoplasia type 2A (MEN 2A). These markers and the gene for MEN 2A (MEN2A) are believed to be in one linkage group spanning approximately 15 cM (male). MEN203 and D10S94 were informative and tightly linked to MEN2A with no recombinants observed in 26 meiotic events. D10S15 (MCK2), widely used in DNA genotyping predictions, demonstrated two recombinants in these two families. The use of multiple flanking markers increases both the likelihood of informativeness and the accuracy …

Henry Ford Hospital Medical Journal
Linkage analysis has been performed in four pedigrees with multiple endocrine neoplasia type 2A (MEN 2A) or familial medullary thyroid carcinoma (MTC) using pericentromeric chromosome 10 probes. Important information regarding carrier status has been provided in 10 individuals, many of whom would not have been identified by pentagastrin stimulation testing. We have also used pulsed field gel electrophoresis (PFGE) to link the probes H4JRBP and pMCK2 to a 150 kb fragment. Using PFGE, no evidence was found in DNA from lymphocytes of a major DNA rearrangement in two individuals affected with MEN 2A and an individual with MEN 2B compared …

Henry Ford Hospital Medical Journal
Two serum calcitonin assays with sensitivities ≤ 10 pg/mL were compared to our standard radioimmunoassay (sensitivity 100 pg/mL) in multiple endocrine neoplasia type 2A (MEN 2A) screening. Values from the Nichols displacement radioimmunoassay averaged 38% higher than values from the CIS immunoradiometric assay; values from both were highly correlated, r = 0.845. In three individuals, both of the newer assays revealed abnormalities in pentagastrin tests three to four years before abnormalities were detected by the standard assay. Pentagastrin tests after total thyroidectomy were assayed by the newer methods in patients with medullary thyroid carcinoma (MTC) diagnosed at initial testing (group …

Genetics Of The Multiple Endocrine Neoplasia Type 2b Syndrome, Charles E. Jackson, Robert A. Norum
Henry Ford Hospital Medical Journal
Multiple endocrine neoplasia type 2B (MEN 2B) is similar to MEN 2A in that both autosomal dominant syndromes include medullary thyroid cancers and pheochromocytomas. It is distinct in that MEN 2B patients have much earlier age of onset with more aggressive tumors and mucosa/neuromas of the lips and tongue. The neuromas allow ascertainment generally before age 5. Studies of two and three generations of 14 MEN 2B families disclosed close linkage of the MEN 2B gene to DNA markers to which MEN2A had been linked. Multipoint analysis utilizing additional results in three generations of a 15th family have disclosed a …

Seven members with multiple endocrine neoplasia type 2B from a 15-member family have been followed for 18 years. All affected had the neuroma phenotype in a distribution compatible with autosomal dominant inheritance. The phenotype features have allowed 100% initial and continuing prediction of affected versus nonaffected status in as early as 1.5 years. Among the affected: immunoreactive plasma calcitonin (iCT) concentration was high in 100%; thyroid palpation was false-negative in 71%; and thyroid scintiscan was false-negative in 83%. All had total thyroidectomy, plus lymphadenectomy in three, for bilateral medullary thyroid carcinoma (MTC) or C-cell hyperplasia (in the youngest). None has …

Three patients of a French family demonstrated an association of multiple endocrine neoplasia type 2A (MEN 2A) with a pruritic scapular skin lesion. The lesions are similar to those described as familial cutaneous lichen amyloidosis in unrelated MEN 2A and medullary thyroid carcinoma families, but histological, immunohistochemical, and ultrastructural analysis of skin biopsies from each patient in the French family did not show amyloid deposition. The topography of the lesion follows dermatomes C8-D3. The patients report not only pruritus but also paresthesia and hyperalgesia, and one showed touch hypoesthesia and pain hyperesthesia in the area of the lesion. Such an …

The hereditary conditions of primary cutaneous lichen amyloidosis and multiple endocrine neoplasia type 2 (MEN 2) are rare clinical entities. The initial reports of two families in which the two conditions coincided have led to the identification of at least eight additional families with this clinical syndrome. In this report we describe the clinical features in five of these eight families. The salient feature in these five families is the presence of unilateral (46%) or bilateral (64%) pruritic and lichenoid skin lesions located over the upper portion of the back. Family members describe these skin lesions as intermittently intensely pruritic …

Unusual Features Of Multiple Endocrine Neoplasia, Andrea Frilling, Heinz Becker, Hans-Dietrich Roeher
Henry Ford Hospital Medical Journal
In addition to the common presentations of the multiple endocrine neoplasia (MEN) syndromes, unusual organ involvement as rare manifestations of a single disease may occur. Among our patients we have identified four cases in which unusual features of MEN were present. In the first patient, bilateral adrenal cortical adenoma, parathyroid adenoma, multiple pancreatic tumors, and follicular thyroid carcinoma were observed. The second patient suffered from thymic carcinoid, parathyroid hyperplasia, gastrinoma, and pituitary adenoma. Additionally, one family was discovered in which medullary thyroid carcinoma (MTC), Hirschsprung's disease, and pheochromocytoma occurred and another family had MTC and ovarian cancer. Based on these …

Henry Ford Hospital Medical Journal
A multifactorial analysis of morphological findings was performed on 153 cases of medullary thyroid carcinoma (MTC). The aim of the study was to utilize histological criteria to discriminate between MTC associated with multiple endocrine neoplasia type 2A (MEN 2A) and that associated with the inherited MTC only syndrome. The presence of fusiform cells associated with several other markers seemed to he more predictive of MEN 2A. A comparison of inherited MTC only and sporadic MTC only showed fusiform cells to be significantly less common in inherited MTC only. These results suggest that the inherited MTC only syndrome is a distinct …

Henry Ford Hospital Medical Journal
The frequency and significance of cervicomediastinal lymph node metastases have been investigated in 82 medullary thyroid carcinoma (MTC) patients retrospectively comparing two surgical techniques of lymph node dissection: selective lymphadenectomy (n = 63) versus compartment-oriented microdissection (n = 35). No positive correlation was observed between primary tumor size and the number of lymph node metastases. Inpatients with lymph node metastases proven histologically, 42% showed only cervical involvement (35% unilateral—type A, 7% bilateral—type B, and 22% cervicomediastinal lymph node involvement (15% cervico-unilateral and mediastinal—type C, 7% cervicobilateral and mediastinal—type D). Biochemical cure was 83% in node-negative patients but only 21% in …

We have followed a family with multiple endocrine neoplasia type 2A for 18 years. Four members have undergone total thyroidectomy for medullary thyroid carcinoma or C-cell hyperplasia, and one has required bilateral adrenalectomy for pheochromoctyoma. None has developed hypercalcemic hyperparathyroidism, although parathyroid hormone levels were relatively high prethyroidectomy and fell postoperatively in the patients with high calcitonin levels. In three of the four cases, intestinal calcium absorption decreased following thyroidectomy.

Henry Ford Hospital Medical Journal
In persistent, clinically inapparent medullary thyroid carcinoma, microsurgical dissection of all lymph node compartments of the neck was performed. Between August 1988 and September 1991, 28 cases (mean age 43.3 years) were treated with 38 surgical interventions. Twenty patients had the sporadic form and eight patients the familial form. Unilateral neck dissection resulted in normalization of serum calcitonin (CT) levels even after pentagastrin stimulation in two patients whereas 16 patients exhibited abnormal CT stimulation tests. Eight of ten patients who had bilateral neck dissections had positive pentagastrin test results after surgery. The main postoperative complications included loss of local cutaneous …

Henry Ford Hospital Medical Journal
To investigate the role of primary and/or secondary modified radical neck dissection (MRND) in patients with medullary thyroid carcinoma (MTC), follow-up data on 43 patients operated on between 1972 and 1983 were analyzed retrospectively; patients included 16 with sporadic MTC (group 1) and 27 with multiple endocrine neoplasia type 2 (group 2). Primary surgical therapy consisted of (near-) total thyroidectomy and limited lymph node dissection: one patient in group 1 and two in group 2 underwent primary MRND. Positive nodes were found in nine patients of group 1 and in 12 of group 2. Calcitonin (CT) was raised postoperatively in …
