On which chromosome is the BCL2 gene located?

The BCL2 gene is located on chromosome 18. This gene plays a crucial role in regulating apoptosis, or programmed cell death, and acts as an oncogene when involved in certain types of cancers, particularly follicular lymphoma. Understanding the chromosomal location of genes like BCL2 is essential for molecular biology, as it helps in identifying genetic abnormalities associated with diseases, designing targeted therapies, and interpreting test results in a clinical context. This makes the identification of the correct chromosome important for diagnostics and research in cancer biology.
