Mismatch repair enzyme deficiency is, as we commonly know, associated with genetic abnormalities like Lynch syndrome (hereditary nonpolyposis colorectal cancer). These are few patients, younger patients with a genetic predisposition. Another way to lose mismatch repair enzymes is by methylation of a ...
Based on the clinical trial information, PD-L1 expression, tumor mutation burden (TMB), microsatellite instability-high (MSI-H) and mismatch-repair deficiency (MMR) have been identified as predictive biomarkers for anti-PD-1/PD-L1 antibody therapies[107,108,109,110,111]. Although biomarkers of...
MMR mismatch repair, MSI-H microsatellite high instability, MSI-L microsatellite low instability, MSS microsatellite stability Full size imageColorectal cancer MSI is closely related to colorectal cancer (CRC), and some studies have found MS loci related to CRC. Saeterdal et al. [36] clarified ...

Emerging data also suggested that predictive markers based on immunoprofiling and mismatch repair deficiency may be of clinical use. In conclusion, the use of combination approaches to treat patients with melanoma, as well as other cancers, is no longer a just a wish for the future but is ...
In the field of sporadic CRC, the BRAF mutation is strongly associated with MMR deficiency. Considering breakthrough results of immune checkpoint inhibitors in dMMR repair tumors, determination of the MMR status appears to be mandatory. Given the dramatic prognosis conferred by the BRAF mutation, ...
mismatch repair, and other mutations in tumor suppressor genes such asTP53or proto-oncogene likeKRASoccur gradually. However, in sporadic type, genetic changes and interactions that lead to tumorigenesis usually occur with aging. Inflammatory related type of colorectal cancer is called colitis associated...
Lynch syndrome (LS) can be strictly defined by the presence of pathogenic germline mutation in one of the four major DNA mismatch repair (MMR) genes MLH1, MSH2, MSH6, and PMS2. This deficiency in MMR function (dMMR) confers a significantly elevated lifetime risk of CRC to patients with ...
Severe combined immunodeficiency (SCID) is a potentially life-threatening genetic disorder that inhibits the body's ability to fight infections. Learn about the causes, symptoms, and treatment of SCID, which is a deficiency of B and T cells, which are the two major weapons of the ...
What disease is caused by silent mutation? Likewise, silent mutations that cause such skipping of exon excision have been identified in genes thought to play roles in genetic disorders such asLaron dwarfism, Crouzon syndrome, β+-thalassemia, and phenylalanine hydroxylase deficiency (phenylketonuria (...
