New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...

Most cancers originate from genetic abnormalities, specifically the accumulation of somatic mutations. These mutations accumulate in normal cells in all organs of healthy individuals and are driven by ...

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Recent studies have advanced our understanding of the somatic mutation landscapes of phenotypically normal tissues, including blood 1, esophagus 2,3, colon 4,5,6,7 ...

Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth. By testing every possible mutation in a critical hotspot, they found that ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

Blood stem cells with driver mutations may be more likely to survive during clonal expansion. Some of these driver mutations have been linked with cancer in other settings. Gene therapy has the ...

Acute myeloid leukemia often involves a mutation of the FLT3 gene. Although this does not affect AML symptoms, it can affect the survival rate. Acute myeloid leukemia (AML) is a type of cancer that ...
