Chromosomal Aberrations

Chromosomal aberrations are changes in the normal structure or number of chromosomes in a cell. These can occur when chromosomes break, rearrange, or gain or lose whole chromosomes during cell division. Such alterations can lead to genetic disorders or diseases, including cancers and conditions like Down syndrome. Chromosomal aberrations can be caused by various factors, including environmental exposure, radiation, and errors in DNA replication. Understanding these changes is crucial for diagnosing genetic diseases and developing potential treatments.
