Genetic
1859, Germany/United Kingdom (early European surgical and pathological reports)
Familial adenomatous polyposis, a hereditary condition characterized by the development of numerous polyps throughout the colon, was recognized clinically long before its genetic basis was understood. Nineteenth-century surgeons and pathologists began documenting families in whom colorectal polyps and cancers appeared across multiple generations, gradually constructing a picture of inherited susceptibility. The twentieth century brought the chromosomal and molecular discoveries that transformed this clinical observation into a landmark in the history of cancer genetics.
Historical Narrative
The earliest recognizable accounts of what would later be called familial adenomatous polyposis appeared in European surgical and pathological literature in the mid-nineteenth century. German and British physicians began reporting patients, often young adults, who were found at surgery or autopsy to harbor extraordinary numbers of polyps carpeting the inner lining of the large intestine. These reports noted the frequent and rapid progression of such cases to malignancy, a pattern that struck observers as distinct from the isolated polyps occasionally encountered in older patients.
The English surgeon Harrison Cripps published a pivotal paper in 1882 describing two siblings who both suffered from diffuse polyposis of the colon and subsequently died of colorectal cancer while still in their twenties. Cripps drew explicit attention to the familial pattern, raising the possibility that whatever caused the condition could be transmitted within families, though the mechanisms of hereditary transmission remained entirely obscure to him.
American physician William Lockhart-Mummery, working at St. Mark's Hospital in London in the early twentieth century, became one of the most important figures in documenting the hereditary nature of the condition. Over decades of surgical practice, Lockhart-Mummery and his colleagues assembled family pedigrees showing the condition appearing in parent and child across successive generations, a pattern consistent with what geneticists, following Mendelian principles, were beginning to describe as autosomal dominant inheritance. St. Mark's Hospital maintained a registry of affected families that would eventually become one of the world's most valuable resources for studying the condition.
The formal application of Mendelian genetics to familial polyposis gained traction in the 1920s and 1930s as physicians such as Eldon Gardner began recognizing that some families showed not only colonic polyps but also benign tumors of bone, skin, and soft tissue. Gardner's detailed descriptions in the 1950s of families with this constellation of findings led to what was called Gardner syndrome, a name used for decades before investigators concluded that it represented a variant manifestation of the same underlying hereditary condition rather than a separate disease.
The major molecular turning point came in 1986 and 1987, when cytogeneticists studying patients with the condition identified consistent deletions on chromosome 5. Researchers including Raymond White and Yusuke Nakamura, working with large family datasets, used newly developed restriction fragment length polymorphism techniques to localize the responsible gene to the long arm of chromosome 5. The actual gene, named APC for adenomatous polyposis coli, was isolated and characterized in 1991 by teams led by Bert Vogelstein at Johns Hopkins and by researchers in Japan, marking a defining moment in the molecular genetics of inherited cancer.
Vogelstein's broader research program used familial adenomatous polyposis as a model for understanding the stepwise accumulation of genetic mutations driving colorectal cancer more generally, establishing foundational concepts about tumor suppressor genes that reshaped cancer biology in the final decade of the twentieth century.
