Mismatch repair (MMR) testing is one of the most important tests performed on endometrial cancer, the cancer that starts in the lining of the uterus. Every newly diagnosed endometrial cancer should be tested for this biomarker. The result tells your doctor whether the cancer’s internal DNA repair system is working properly. If it isn’t — …

MMR-deficient, often written as dMMR, means that one or more of the proteins responsible for repairing mistakes in a cell’s DNA are missing or not working properly. When these repair proteins are lost, errors in DNA can accumulate over time, contributing to the development of cancer. Finding dMMR in a tumour has important implications for …

PMS2 is a gene that produces a protein involved in repairing mistakes in a cell’s DNA. It is one of four key mismatch repair (MMR) proteins — along with MLH1, MSH2, and MSH6 — that work together to find and fix small errors that occur when DNA is copied during cell division. PMS2 and MLH1 …

MLH1 is a gene that produces a protein involved in repairing mistakes in a cell’s DNA. It is one of four key mismatch repair (MMR) proteins — along with PMS2, MSH2, and MSH6 — that work together to find and fix small errors that occur when DNA is copied during cell division. MLH1 and PMS2 …

What are mismatch repair proteins? Mismatch repair proteins (MMR) are a system inside all normal, healthy cells for fixing mistakes in our genetic material (DNA). The system is made up of different proteins and the four most common are called MSH2, MSH6, MLH1, and PMS2. The four MMR proteins MSH2, MSH6, MLH1, and PMS2 work …

Endometrioid carcinoma of the ovary is a type of ovarian cancer that resembles endometrioid carcinoma of the uterus when examined under the microscope. It develops from epithelial cells that line the ovary. This tumour accounts for about 10% of ovarian carcinomas. Many cases are diagnosed at an early stage and are confined to the ovary …
