A single team of researchers from around the globe conducting two different studies has found more genes related to human intelligence and more that are associated with neuroticism. They have published separate papers outlining ...
For many inherited diseases, such as cystic fibrosis or Huntington disease, the disease-causing genetic mutation damages or removes a protein that has an essential role in the body. This protein defect is the root cause of ...

(Medical Xpress)—A new study in mice has shown that genetically engineered bacteria can protect against inflammatory bowel disease (IBD), which includes a host of conditions including ulcerative colitis and Crohn's disease.
Researchers have developed a functional precision medicine approach that targets cancer by combining genetic testing with a new way to test individual drugs on tumor samples. The results of the clinical study were published ...

Genetic testing allows the genetic diagnosis of vulnerabilities to inherit diseases, and can also be used to determine a person's ancestry. Normally, every person carries two copies of every gene, one inherited from their mother, one inherited from their father. The human genome is believed to contain around 20,000 - 25,000 genes. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. Genetic testing identifies changes in chromosomes, genes, or proteins. Most of the time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. Several hundred genetic tests are currently in use, and more are being developed.
Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling.
