Study of new mutations may show how cancers grow

Scientists have discovered two new genetic mutations that occur together in 71 percent of malignant melanoma tumors, an aggressive and deadly cancer of the skin, a study said. The mutations, detected in a part of the cancer genome that controls genes but not in the genes themselves, could aid understanding…

Amino acids could treat rare form of autism: study

CHICAGO — A common dietary supplement could treat a rare form of autism which has been found to be linked to an amino acid deficiency, a study published Thursday in the journal Science has found. US researchers were able to isolate a genetic mutation in some autism patients which speeds…

Study: Risk of genetic abnormalities in babies rises as father’s age increases

Do older fathers doom their children to genetic disease? This is the question raised by a new study that says older men produce moregene mutations in the children they sire, boosting their risk ofschizophrenia and autism and possibly other diseases. A father’s age is by far the biggest factor determining the rate of…

Researchers untangle complex genetic processes underlying breast cancer

Researchers at the Wellcome Trust Sanger Institute have begun to unravel the complex processes that cause breast cancer, identifying a variety of genetic mutations that emerge during tumor growth. Their research found that a variety of naturally-occurring mutations in the DNA cells can initiate different sequences of mutations that eventually…
