Disease Genes Effect May Be Overcome by Other Gene Mutations
A first-of-its-kind study, performed in the model yeast Saccharomyces cerevisiae, shows how “bad genes aren’t always bad news” in that the disease-causing effects of mutations in certain genes can be overcome by suppression-mutations in certain other genes. The study opens a new way for better understanding how some people naturally stay healthy despite having disease-causing mutations, and potentially a new path to better diagnostics and therapies of genetic disorders.

Vascular Development Gene Helps Protect Against Stroke Damage
Using CRISPR gene-editing technology and genetically engineered mice, scientists have discovered that a “collateral vessels” gene, Rabep2, protects against stroke damage. Variants of the human version of the gene may help explain why people differ so much in their ability to survive artery blockages. More...15 Nov 2016
Early Childhood Screening Helps Prevent Heart Attacks
Familial hypercholesterolemia (FH) is a genetic disorder characterized by high cholesterol levels and is the main inherited cause of early heart disease and without preventive medication young FH adults has about a 10-fold increased risk of a heart attack before the age of 40. More...08 Nov 2016
Gene Abnormality Found to Underlie Rare Neurological Disease
Researchers have discovered that malfunctioning variants of a gene encoding a mitochondrial protein results in a group of related neurological syndromes classified as conditions of unknown origin. The study sheds new light on causes of such diseases and opens a door for developing better diagnostic tools and treatments. More...03 Nov 2016
