WebThe O 6 -methylguanine-DNA methyl-transferase (MGMT) gene is located on chromosome 10q26.3, and encodes a highly evolutionarily conserved and ubiquitously expressed enzyme involved in DNA repair [1]. MGMT acts by removing alkyl adducts from the O 6 position of guanine at DNA level, thus antagonizing the lethal effects of alkylating agents. Web13 apr. 2024 · This pattern does not distinguish between loss of protein expression due to promoter hypermethylation and gene mutation in an MMR gene mutation associated with Lynch syndrome. Therefore, reflex BRAF and MLH1 promoter hypermethylation molecular testing were performed.
