Abstract Summary
Researchers compared genetic mutations in colorectal tumors from familial adenomatous polyposis (FAP) patients versus sporadic cases. While APC and KRAS mutation frequencies were similar, FAP tumors showed a distinct pattern: 75% acquired a second APC mutation after inheriting one, and 10% gained a third “hit”—revealing unexpected genetic complexity in inherited colon cancer development.
Why Brain? 🧠
Study reveals FAP patients can acquire ‘three-hit’ APC mutations during colorectal cancer development, showing both inherited and acquired genetic changes drive tumor progression similarly to sporadic cases.
