A cryptic paracentric inversion ofMSH2exons 2–6 causes Lynch syndrome

Abstract excerpt

Lynch syndrome is an autosomal dominant disorder that predisposes carriers of DNA mismatch repair (MMR) gene mutations to early-onset cancer. Germline testing screens exons and splice sites for mutations, but does not examine introns or RNA transcripts for alterations. Pathogenic mutations have not been detected in ~30% of suspected Lynch syndrome cases with standard screening practices. We present a 38-year-old...
