We describe an 11 year old girl with a de novo unbalanced t(X;10) that resulted in a deletion of Xq26-->Xqter and a trisomy of 10q21-->10qter. Her clinical features were of distal trisomy 10q, but she lacked the cardiovascular and renal malformations observed in duplications of 10q24-->10qter and had only moderate mental retardation. X inactivation was assessed on peripheral blood lymphocytes b...

Endometriosis has a genetic component, and significant linkage has been found to a region on chromosome 10q. Two candidate genes, EMX2 and PTEN, implicated in both endometriosis and endometrial cancer, lie on chromosome 10q. We hypothesized that variation in EMX2 and/or PTEN could contribute to the risk of endometriosis and may account for some of the linkage signal on 10q. We genotyped single ...

Relatively frequent losses of heterozygosity on chromosomes 5q, 6q, and 10q, in addition to loss of heterozygosity on the short arm of chromosome 3, have been observed in renal cell carcinomas. As the first step toward isolation of tumor suppressor genes on these three chromosomal arms, we used six restriction fragment length polymorphism markers for 5q, nine for 6q, and eight for 10q to identi...

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...

Proximal 10q duplication is a well-defined but rare genetic syndrome. Duplication of proximal segments of the long arm of chromosome 10 results in a pattern of malformations, which are distinct from those of the more common distal 10q trisomy syndrome. The present study describes the case of a boy with phenotypic abnormalities (severe central hypotonia, mild ataxia, moderate developmental delay...

Since its description in 1965, distal 10q trisomy has become recognised as a well defined, although rare syndrome, almost always the result of an unbalanced translocation. Typical features consist of psychomotor delay, a distinctive dysmorphic appearance, growth retardation, and, in some cases, cardiac, renal, and ocular abnormalities.

A female infant with karyotype 46,XX,rec(10),dup p inv(10)(p11.2q25.2)mat is presented. She had both duplication of 10p and deletion of distal 10q, but only had the constellation of specific features characteristic of duplication of 10p.

PURPOSE There is a need for improved subclassification of urothelial carcinoma (UC) at diagnosis. A major aim of this study was to search for novel genomic subgroups. EXPERIMENTAL DESIGN We assessed 160 tumors for genome-wide copy number alterations and mutation in genes implicated in UC. These comprised all tumor grades and stages and included 49 high-grade stage T1 (T1G3) tumors. RESULTS ...
