A rare non-Robertsonian translocation involving chromosomes 15 and 21.
CONTEXT Robertsonian translocations (RT) are among the most common balanced structural rearrangements in humans and comprise complete chromatin fusion of the long arm of two acrocentric chromosomes. Nevertheless, non-Robertsonian translocation involving these chromosomes is a rare event. CASE REPORT We report a de novo unbalanced translocation involving chromosomes 15 and 21. The newborn was ...
متن کاملLarge-scale transcriptional activity in chromosomes 21 and 22.
The sequences of the human chromosomes 21 and 22 indicate that there are approximately 770 well-characterized and predicted genes. In this study, empirically derived maps identifying active areas of RNA transcription on these chromosomes have been constructed with the use of cytosolic polyadenylated RNA obtained from 11 human cell lines. Oligonucleotide arrays containing probes spaced on averag...
متن کاملComplex Variant of Philadelphia Translocation Involving Chromosomes 9, 12, and 22 in a Case with Chronic Myeloid Leukaemia
Chronic myeloid leukemia (CML) is a hematopoietic stem cell disorder included in the broader diagnostic category of myeloproliferative neoplasms, associated with fusion by BCR gene at chromosome 22q11 to ABL1 gene at chromosome 9q34 with the formation of the Philadelphia (Ph) chromosome. In 2-10% of CML cases, the fusion gene arises in connection with a variant translocation, involving chromoso...
متن کاملSNPs on human chromosomes 21 and 22 -- analysis in terms of protein features and pseudogenes.
SNPs are useful for genome-wide mapping and the study of disease genes. Previous studies have focused on SNPs in specific genes or SNPs pooled from a variety of different sources. Here, a systematic approach to the analysis of SNPs in relation to various features on a genome-wide scale, with emphasis on protein features and pseudogenes, is presented. We have performed a comprehensive analysis o...
متن کاملPrader-Willi syndrome in siblings, due to unbalanced translocation between chromosomes 15 and 22.
In a family in which the father carried a balanced translocation between chromosomes 15 and 22 two of his children had Prader-Willi syndrome and an unbalanced chromosome complement, having lost the proximal bands from the long arm of chromosome 15. His four other surviving children were normal but carried a balanced translocation.
