Purpose:
Chromosomes are highly structured, dynamic complexes of DNA and protein. The human genome consists of 46 chromosomes (22 paired autosomes and 2 sex chromosomes). Cytogenetic analysis provides a means to identify, as well as describe, chromosomes and disorder-related aberrations. The purpose of this article is to 1) introduce chromosome structure and alterations, 2) describe the technical fundamentals of cytogenetic analysis, and 3) provide a brief overview of the clinical applications of this technology.
