Colored blocks designate how genetic material can be changed by duplicating or deleting segments. The original strand shows boxes with colors red, green, yellow, blue, red, green, and gray. The strand with a deletion shows red, yellow, blue, red, green, and gray. The strand with a duplication shows red, green, green, yellow, blue, red, green, and gray.

Two examples of CNVs are “deletion” and “duplication.” These variations can result in loss of function of critical genes, increasing the risk or setting the stage for cancer’s progression. You can use your data science skills to process these data, aligning your “reads” to a reference genome, filtering out background noise, mapping CNVs to known genes and regulatory regions, and visualizing the results. This enables you to further assess the biological impact of these changes.
