Abstract Early T-cell precursor phenotype acute lymphoblastic leukemia (ETP-ALL) is a subtype of T-ALL with unique immunophenotype and genetic abnormalities distinct from conventional T-ALL. A subset T lymphoma (T-LLy) also demonstrates the early may be counterpart ETP-ALL. Unlike ETP-ALL, incidence, clinical features, genomic features ETP-LLy are unknown. We reviewed immunophenotyping data 218...
Prevalence of health behaviors among adults with disabilities may vary by disability measure. We used data from the 2011-2015 National Health Interview Survey to estimate prevalence of physical inactivity by disability status using 2 measures of disability: Basic Actions Difficulty questions (BADQ) and a standard 6-question measure (6Q). Disability prevalence (BADQ, 31.1%; 6Q, 17.5%) and inacti...
Cytogenetic studies were performed on ML cell lines (ML-1, -2, and -3), as well as on the leukemic cells of a patient from whom the ML cells were derived. The ML-1 cell line showed numerical and structural cytogenetic changes, i.e., -Y, 1p-, 6q-, 11q-, +12, +13q+, 14q-, and 17q-. The ML-2 cell line had two copies of the 13q+, whereas the ML-3 cells contained three clones, i.e., 47,X,-Y,1p-,6q-,...
Chronic lymphocytic leukemia (CLL) is most characteristically associated with the cytogenetic abnormalities +12, 13q14, and 14q32. Recently abnormalities of chromosome 6 have been reported in patients with mantle zone lymphoma, CLL mixed type, and a CLL variant with larger prolymphocytoid cells in the peripheral blood. The purpose of this study was to review the cases of CLL karyotyped at the U...
Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focused genetic screen, we identified SESTRIN1 as a relevant target of the 6q deletion and demonstrate tumor suppression by SESTRIN1 in vivo. Mor...
Interstitial deletions of the long arm of chromosome 6 are relatively rare, with fewer than 100 cases reported. Phenotypic variation is in large part due to differences in size and location of the segmental aneuploidy. We report three new patients with interstitial deletions of chromosome 6q defined at the molecular level by array comparative genomic hybridization (array CGH). In two of three c...
Clonal chromosomal changes in multiple myeloma (MM) and related disorders are not well defined, mainly due to the low in vivo and in vitro mitotic index of plasma cells. This difficulty can be overcome by using comparative genomic hybridization (CGH), a DNA-based technique that gives information about chromosomal copy number changes in tumors. We have performed CGH on 25 cases of MM, 4 cases of...
Karyotypes of 107 cases with adult T-cell leukemia/lymphoma (58 male, 49 female; 81 acute or lymphoma type, 26 chronic or smoldering type) were reviewed by a panel of cytogeneticists and were correlated with the subtypes of the disease. Clonal chromosome abnormalities were found in 103 (96%) cases, of which four had hypotetraploidy. Of 184 numerical abnormalities in the remaining 99 cases with ...
