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 ...

Each chromosome pair viewed in a karyotype appears to have its own distinct "bar code" of bands. What changes do scientists look for in a karyotype when diagnosing diseases and disorders?

A woman got routine bloodwork during her second pregnancy and was shocked when the test results came back: It suggested her ...

A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities ...

[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 ...

Now that certain human disorders have been linked with chromosome abnormalities, it is desirable to examine large numbers of cells for such abnormalities. A computer regime has been devised for ...

Microarray analysis identifies more chromosome abnormalities than traditional karyotyping in prenatal testing. Microarrays will also identify findings of unclear clinical significance that should ...

Many genes may be transferred between chromosomes. Such translocation mutations can cause disorders of growth, development, and function of the body's cells and systems. Human cell nuclei have 23 ...
