摘要: Background: A 40 kb ancestral germline duplication upstream of the GREM1 gene was reported in Ashkenazi families with hereditary mixed polyposis syndrome (HMPS). Objective: Assess contribution mutation to familial colorectal cancer (CRC) Ashkenazim. Methods: Jewish individuals (n = 472 155 males, 317 females) were genotyped for duplication, 194 CRC, 131 had other types (endometrial, pancreatic and ovarian) that show a syndromic association 147 cancer-free suggestive family history CRC. Results: One carrier found who fulfills Amsterdam criteria Lynch Syndrome (LS). The prevalence this amongst LS Ashkenazim is 0·7%. Conclusion: If validated additional studies it seems rational recommend look founder multiple polyps and/or fulfill LS.
