Yeast mimics severity of mutations leading to fatal childhood illness
Scientists report that human gene mutations expressed in yeast cells can predict the severity of Batten Disease, a fatal nervous system disorder that begins during childhood. view more (2008-12-22)
No test needed for hand-foot genital syndrome in women without HOXA13 gene mutation
Hugh S. Taylor, M.D., professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale, and colleagues have found that women without mutations of the HOXA13 gene do not need to be subjected to x-rays and other tests for a rare condition called hand-foot genital syndrome. view more (2009-10-20)
Survival of the fittest: even cancer cells follow the laws of evolution
Scientists from The Institute of Advanced Studies at Princeton and the University of California discovered that the underlying process in tumor formation is the same as for life itself-evolution. view more (2008-08-04)
Cystic fibrosis testing -- next steps
Three reports describing advances in cystic fibrosis genetic testing appear in the May 2009 issue of The Journal of Molecular Diagnostics. view more (2009-04-28)
Targeting lung cancer
As reported in the June 1 issue of G&D, Drs. Katerina Politi, Harold Varmus and colleagues at the Memorial Sloan Kettering Cancer Center in New York have developed a novel animal model of lung adenocarcinoma that will be of great use in testing the efficacy of targeted therapies against human lung cancer. view more (2006-05-18)
Study Confirms Value Of Family-history Knowledge For Young Women With Breast Cancer (p 1101)
A UK study published as a research letter in this week's issue of THE LANCET highlights the importance of detailed family-history knowledge to help identify women with pathogenic gene mutations for breast cancer. Women who carry mutations of BRCA1 and/or BRCA2 genes have a much higher lifetime risk of breast cancer-up to 80%-compared with... view more... (2003-03-26)
Poor prognosis linked to BRCA1 mutations - but may be improved by chemotherapy
Breast cancer patients have a lower chance of long-term survival if they carry an inherited mutation in the BRCA1 gene, according to research published in Breast Cancer Research this week. However, the poor prognosis associated with the mutated gene is mitigated by chemotherapy. The breast cancer susceptibility genes, BRCA1 and BRCA2, were... view more... (2003-10-20)
A new kind of mutation could explain numerous phenotypic variations in various species
The authors describe the discovery of a novel class of mutations that disrupt the function of a gene and thereby cause a specific phenotype. The mutation created the appearance of an "illegitimate" microRNA (miRNA) recognition site in a gene that did not have it in its normal form. view more (2006-06-06)

Sun exposure early in life linked to specific skin cancer gene mutation
Skin cancers often contain different gene mutations, but just how these mutations contribute to the cause of melanomas has been a mystery. view more (2007-06-11)
Exposure to organic dissolvents may cause carcinogenic mutations
A study led by Universitat Autònoma de Barcelona researchers has shown that exposure to hydrocarbon-based organic dissolvents may provoke mutations in the k-ras oncogen, a gene which facilitates the appearance of tumours when it has mutated. The relationship has been demonstrated in pancreatic cancer patients who had been exposed to the... view more... (2002-02-11)
Mutation rate in a gene on the X chromosome holds promise for testing cancer risk
A new study to detect an elevated rate of mutations in a gene on the X chromosome holds promise for developing a test that could identify individuals at risk for developing cancer. view more (2005-09-16)
University of Chicago study overturns conventional theory in evolution
New data suggest that the accumulation of genetic changes is not solely determined by natural selection. A study by University of Chicago researchers contradicts conventional theory by showing that the percentage of mutations accepted in evolution is also strongly swayed by the speed at which new mutations arrive at a gene: the faster the speed of... view more...

A fly lamin gene is both like and unlike human genes
Lamins are intermediate filament proteins that make up a matrix underlying the nuclear membrane. view more (2007-06-13)
New gene linked to bipolar disorder
A new gene linked to both depression and bipolar disorder has been identified by UCL (University College London) and Danish researchers. view more (2006-10-04)
Researchers identify promising gene target for neuroblastoma therapy
Researchers at Dana-Farber Cancer Institute have identified a set of previously unknown mutations in a single gene in 8 percent of neuroblastomas, tumors of the nervous system that occur in young children and account for approximately 15 percent of all childhood cancer deaths. view more (2008-10-16)
PINK1 protects from Parkinson's
Parkinson disease (PD) is a common neurodegenerative disease characterized by the selective loss of midbrain dopaminergic neurons. view more (2007-06-19)
Study uncovers mutation responsible for Noonan Syndrome
Scientists have discovered that mutations in a gene known as SOS1 account for many cases of Noonan syndrome (NS), a common childhood genetic disorder which occurs in one in 1,000-2,500 live births. view more (2006-12-05)
New hereditary gene linked to Parkinson's disease
UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at UCL's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.... view more...

Genetic analysis of cavefish reveals more about evolution
A multi-institutional study offers additional insight into the evolutionary process by examining how albinism evolves in cavefish. view more (2005-12-20)
