Origine du drapeau rouge

DéfinitionFamily pedigree suggestive of Familial Adenomatous Polyposis (FAP) or the attenuated FAP (AFAP) / Gardner-variant spectrum: any of (a) a family member with a known pathogenic APC variant; (b) classic FAP phenotype — >100 colorectal adenomatous polyps in the proband or a first/second-degree relative; (c) attenuated FAP phenotype — 10-100 colorectal adenomas in a relative plus family history of CRC under 60; (d) first-degree relative with a confirmed clinical FAP diagnosis; (e) family member with extracolonic FAP / Gardner manifestations (osteomas, epidermoid cysts, congenital hypertrophy of the retinal pigment epithelium [CHRPE], or desmoid tumors). No current personal cancer diagnosis in the individual at risk. Prevention-persona RedFlag (§20 ratification 2026-05-18, v0.2-B hereditary pilot starter).

Notes

v0.2-B hereditary pilot — FAP. Fires on pedigree-based suspicion of FAP / AFAP / Gardner-variant in an asymptomatic individual (no current cancer diagnosis). Engine routes to PreventionPlan recommending: (a) genetic counseling + germline APC panel testing (modern multi-gene panels include MUTYH for MAP differential — note that MUTYH-associated polyposis is autosomal recessive vs autosomal-dominant FAP) via IND-FAP-SUSPICION-PREVENTION-GENETIC-COUNSELING (standard) (b) empirical enhanced surveillance for patients declining testing via IND-FAP-SUSPICION-PREVENTION-ENHANCED- SURVEILLANCE (alternative). Triggers correspond to established FAP-suspicion criteria. Patient profile is expected to carry these as computed booleans from the pedigree input (FHIR FamilyMemberHistory at the data-standards layer; computation is a downstream concern not yet implemented). STUB pending two-Clinical-Co-Lead signoff per CHARTER §6.1 dev-mode exemption. Source-set TODO: NCCN Genetic/Familial High-Risk: Colorectal as a new SRC entity (per scope proposal open question #7 on license posture); American College of Gastroenterology FAP surveillance guidance. Confirmed APC carriers (germline mutation positive...
