Proximal duplications of chromosome 1q are rare chromosomal abnormalities. Most patients with this condition present with neurological, urogenital, and congenital heart disease and short life expectancy. Mosaicism for trisomy 1q10q23.3 has only been reported once in the literature. Here we discuss a second case: a girl with a postnatal diagnosis of a de novo pure mosaic trisomy 1q1023.3 who has...

Cytogenetic markers involving the long arm of chromosome 1 are the most frequently observed karyotypic changes seen in breast cancer. Based on cytogenetic data, we have used polymorphic DNA markers to search for allelic losses at this chromosome region among 48 breast carcinomas. For SPTA1, allelic losses were seen in 6 of 26 (23%) informative carcinomas, while 3 of 13 (23%) and 5 of 19 (26%) i...

A genome screen to identify genes influencing the age at Parkinson disease (PD) onset was completed using 276 families without parkin mutations. Significant evidence of linkage to chromosome 2p near the PARK3 locus (logarithm of odds [lod] = 4.8) was observed. Evidence of linkage was also detected to chromosomes 1q (lod = 3.0) and 8q (lod = 2.6). These data suggest that the genes influencing ag...

Genetic influences on lipid traits have been suggested by numerous studies. In addition to heritability studies, over 50 genome scans have been performed to identify regions of linkage for quantitative lipid levels. Five of these scans have been performed in African Americans (four univariate and one bivariate linkage analysis), but with results that have been largely inconclusive. Linkage anal...

BACKGROUND We comprehensively profiled cytogenetic abnormalities in multiple myeloma (MM) and analyzed the relationship between cytogenetic abnormalities of undetermined prognostic significance and established prognostic factors. METHODS The karyotype of 333 newly diagnosed MM cases was analyzed in association with established prognostic factors. Survival analysis was also performed. RESULT...

Bladder cancer is the ninth most common cancer in the world. Urothelial carcinoma (formerly known as transitional cell carcinoma) comprises the majority of bladder cancers. In order to decipher the genetic alteration leading to the carcinogenesis of urothelial cancer, we performed genome-wide allelotyping analysis using 384 microsatellite markers spanning 22 autosomes together with comparative ...

p32 [also known as HABP1 (hyaluronan-binding protein 1), gC1qR (receptor for globular head domains complement 1q) or C1qbp (complement 1q-binding protein)] has been shown previously to have both mitochondrial and non-mitochondrial localization and functions. In the present study, we show for the first time that endogenous p32 protein is a mitochondrial protein in HeLa cells under control and st...

Genotyping, using plasma proteins or DNA polymorphisms or both, was carried out on 30 families selected through probands with Von Recklinghausen disease. The data provide additional evidence for the exclusion of loci on chromosomes 3 and 5, and chromosome arms 1q, 2p, 4p, 4q, 6q, 7p, 9q, 11p, 11q, and 14q. There was no evidence for genetic heterogeneity at D1S1 (DNF15S2) on chromosome arm 3p, u...
