In a panel of large Caucasian pedigrees, we genotyped markers in eight chromosomal regions previously reported as supporting linkage with type 2 diabetes. We previously reported significant linkage on chromosome 20q (maximum logarithm of odds score [MLS] = 2.79) in this panel. In the present analysis, candidate regions on 1q, 2q, 3q, 5q, 9q, and 10q yielded little evidence for linkage; a region...
Sporadic prostate carcinoma is the most common male cancer in the Western world, yet many of the major genetic events involved in the progression of this often fatal cancer remain to be elucidated. Numerous cytogenetic and allelotype studies have reported frequent loss of heterozygosity on chromosomal arm 10q in sporadic prostate cancer. Deletion mapping studies have unambiguously identified a ...
Previously, we reported evidence of genetic heterogeneity in late-onset familial Alzheimer's disease, based on sex of affected parent, demonstrating linkage to chromosome 10q, a region identified by other groups and implicated as a quantitative trait loci for Abeta levels, in families with an affected mother. Using functional magnetic resonance imaging and a memory encoding task, we now show di...
In an attempt to define chromosomal alterations that are associated with the metastatic phenotype, we investigated a total of 29 metastasizing (pN+) and 19 non-metastasizing (pN0) head and neck squamous cell carcinomas by comparative genomic hybridization (CGH). The analysis indicated that the pN0 tumors carried preferentially overrepresentations of chromosomes 5p, 6p, and 7p and that the pN+ t...
A case of a fetus with multiple malformations is described. The mother showed a 46,XX,rcp(10;22) (p11;p11) karyotype. Amniocentesis at the 16th week of gestation revealed that the male fetus had a der(22) chromosome--that is, he was trisomic for a large part of 10p (10pter leads to 10p11). Clinical findings of cases with 10p, 10q, and mosaic 10 trisomies are briefly reviewed.
We report three new mutations in PTEN, the gene responsible for Cowden disease in five patients with Bannayan-Riley-Ruvalcaba syndrome from three unrelated families. This finding confirms that Cowden disease, a dominant cancer predisposing syndrome, and Bannayan-Riley-Ruvalcaba syndrome, which includes macrocephaly, multiple lipomas, intestinal hamartomatous polyps, vascular malformations, and ...
Comparative genomic hybridization was applied for a comprehensive screening of under- and overrepresentation of genetic material in 13 autoptic small cell lung cancer specimens. The most abundant genetic changes include DNA losses of chromosome arms 3p, 5q, 10q, 13q, and 17p and DNA gains of 3q, 5p, 8q, and 17q. Amplification sites in these tumors were mapped to 22 chromosome bands. The most fr...
Recent studies suggest that insulin-degrading enzyme (IDE) in neurons and microglia degrades Abeta, the principal component of beta-amyloid and one of the neuropathological hallmarks of Alzheimer's disease (AD). We performed parametric and nonparametric linkage analyses of seven genetic markers on chromosome 10q, six of which map near the IDE gene, in 435 multiplex AD families. These analyses r...
