Identification of a novel pathogenic MLH1 mutation and recommended genetic screening strategy: An investigation of three Chinese Lynch syndrome pedigrees

Sign Up to like & get
recommendations! Published in 2020 at "Molecular Genetics & Genomic Medicine"

DOI: 10.1002/mgg3.1295

Abstract: Abstract Background Lynch syndrome (LS) is an autosomal‐dominant disorder that increases the risk of many cancers. The genetic basis of LS is germline mutations in DNA mismatch repair genes. Methods We performed next‐generation sequencing on… read more here.

DOI: 10.1016/j.ygyno.2017.07.003

Abstract: OBJECTIVES To determine the relationship between mismatch repair (MMR) classification and clinicopathologic features including tumor volume, and explore outcomes by MMR class in a contemporary cohort. METHODS Single institution cohort evaluating MMR classification for endometrial… read more here.

DOI: 10.1038/gim.2018.47

Abstract: PurposeConstitutional epimutations are an alternative to genetic mutations in the etiology of genetic diseases. Some of these epimutations, termed secondary, correspond to the epigenetic effects of cis-acting genetic defects transmitted to the offspring following a… read more here.

DOI: 10.1038/s41439-018-0002-1

Abstract: Lynch syndrome, an autosomal dominantly inherited disease, is characterized by an increased risk of developing colorectal cancer. We found a novel germline variant of MLH1 (IVS6+2T>C) that caused Lynch syndrome in a young Japanese patient… read more here.

DOI: 10.1073/pnas.2212870119

Abstract: Significance DNA mismatch repair (MMR) prevents mutations caused by DNA-replication errors and suppresses multiple types of cancers. During MMR, the Mlh1-Pms1 complex is recruited to mispair-containing DNA and nicks the newly replicated DNA strand, targeting… read more here.

DOI: 10.1080/17501911.2025.2579975

Abstract: BACKGROUND A large scale detection of MLH1 methylation is lacking in esophageal cancer. MLH1 is a well-known mismatch repair gene. The mechanism of MLH1 in DNA double strand break (DSB) repair remains unclear. METHODS Esophageal… read more here.

DOI: 10.1093/nar/gkad418

Abstract: DNA mismatch repair (MMR) is essential for correction of DNA replication errors. Germline mutations of the human MMR gene MLH1 are the major cause of Lynch syndrome, a heritable cancer predisposition. In the MLH1 protein,… read more here.

DOI: 10.1111/his.13874

Abstract: Dysplasia in colonic sessile serrated adenomas (SSAs)/sessile serrated polyps often shows loss of MLH1 expression as determined with immunohistochemistry, but the significance of loss of MLH1 expression in non‐dysplastic crypts in these polyps is less… read more here.
