How do scientists find their way around a chromosome? With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Aa Aa Aa Most ...

Chromosome abnormality is the condition in a cell or organism where the number of chromosomes or the structure of any chromosome differs from the normal karyotype. When the variant genotype is not ...

7 It therefore appeared reasonable to investigate systematically the chromosomes in a group of patients to determine if any abnormalities could be found in this condition. Constitutional aplastic ...

[44] Combining a limited karyotype with the more objective microarray data will allow for a clearer interpretation for any disease-causing chromosome abnormalities, if any, in the fetus undergoing ...

The study builds upon Navin's previous work on the Human Breast Cell Atlas, which profiled over 714,000 cells to generate a comprehensive genetic map of normal breast tissue at the cellular level.

But the approach overlooked the impact of large-scale chromosomal abnormalities and how they might affect gene function and cancer cell behavior. While sequencing DNA purified from bulk tumor samples ...
