PIK3CA

PIK3CA is a gene that encodes for a subunit of the enzyme phosphatidylinositol 3-kinase (PI3K), which is involved in crucial cellular processes such as growth, proliferation, and survival. Mutations in the PIK3CA gene are commonly found in various types of cancers, including breast, colorectal, and endometrial cancers. These mutations can lead to the overactivation of the PI3K pathway, promoting uncontrolled cell division and tumour growth. Detecting PIK3CA mutations in cancer patients helps guide targeted therapy decisions, as drugs specifically designed to inhibit the PI3K pathway can be more effective in treating tumours with these genetic alterations. Understanding PIK3CA and its role in cancer biology is vital for developing personalized treatment plans and improving patient outcomes through precision medicine.
