For example, the MSH3 protein normally helps the cell monitor its DNA for potential mutations, but loops in the DNA formed by extra CAGs can confuse this protein into expanding the CAG repeat.

A mutation is any detectable and heritable change in nucleotide sequence that causes a change in genotype and is transmitted to daughter cells and succeeding generations. Splice-site creating ...

Jan. 15, 2025 — A cutting-edge molecular approach provides a detailed picture of the biological pathways associated with childhood obesity and metabolic dysfunction, and identifies environmental ...

Genetics is the branch of science concerned with genes, heredity, and variation in living organisms. It seeks to understand the process of trait inheritance from parents to offspring, including ...

In addition to opening a new window into how human genetic mutations can operate, the researchers hope that their insights lead to new strategies that improve or ultimately save the lives of people ...
