Rphic variants of these genes were found to be significantly connected with breast, pancreatic, colorectal and ovarian cancers [614]. However, towards the ideal of our understanding, none of the variants identified in this study were previously reported to be related with any other cancer, except rs7003908. MSH3 upon phosphorylation by ATM/ATR initiates DNA mismatch repair with MSH2 and directs Ladostigil Epigenetic Reader Domain downstream MMR events, which includes strand discrimination, excision, and re-synthesis with MLH1 and PMS1 [36], [65]. XRCC5 with XRCC6 forms a dimer and increases the affinity of PRKDC, the catalytic subunit of DNA-PK [DNA-dependent serine/threonine protein kinase] [66]. It plays a number of important roles like, recognition and recruitment of other elements to DSB and phosphorylation of numerous transcription variables like p53 [67]. Numerous other phosphorylating substrates of PRKDC have also important function in cancer, like, c-Myc, PARP, c-JUN [680]. MRE11A, among the partners of MRE11A-RAD50-NBN complex involved in DSB repair, have also function in telomerase integrity and meiosis. The functional implications of either the associated intronic SNPs or their linked functional SNPs in these genes are needed to be investigated in future.DNA Repair Gene Polymorphisms and Oral CancerPLOS 1 | plosone.orgDNA Repair Gene Polymorphisms and Oral CancerFigure 2.

As a multifactorial disease, the pathogenesis of OM is complex. Determined by earlier analysis, numerous factors are believed to contribute for the development and persistence of OM such as: environmental factors including smoking and kind of chil.
