Copy Number Variations

Copy Number Variations (CNVs) are differences in the number of copies of a particular gene or region of DNA that individuals have. While most people have two copies of each gene (one from each parent), CNVs can result in having more or fewer copies. These variations can influence traits, susceptibility to diseases, and response to medications. CNVs are a natural part of human genetic diversity, and understanding them helps researchers study genetic disorders and individual differences in health and disease risks.
