Researchers in Italy say they've found a cholesterol-blocking gene in three southern Italian families.
The families, from Sicily and Calabria, are the first white bearers of the gene, ANSA said in a news release.
ANSA said the mutated gene is found in 2 percent of African-Americans.
Maurizio Averna of Palermo University said the discovery may help scientists find new ways of keeping cholesterol low and averting heart disease.
The study was published by the American Heart Association, ANSA said.

Middle Eastern families yield intriguing clues to autism
Research involving large Middle Eastern families, sophisticated genetic analysis and groundbreaking neuroscience has implicated a half-dozen new genes in autism. More importantly, it strongly supports the emerging idea that autism stems from disruptions in the brain's ability to form new connections in response to experience – consistent with autism's onset during the first year of life, when many of these connections are normally made.
Mayo Clinic spearheads research to discover unsuspected gene for atrial fibrillation
Mayo Clinic researchers have found a gene mutation linked to one family's hereditary form of atrial fibrillation. Researchers hope this discovery will lead to better understanding of the disease and, eventually, better ways to predict, prevent and treat the heart rhythm problem.
Genetic variants of USF1 are associated with the increased risk for cardiovascular disease
Cardiovascular diseases (CVD) are major contributors to morbidity and mortality worldwide. Several interacting environmental, biochemical, and genetic risk factors can increase disease susceptibility. While some of the genes involved in the etiology of CVD are known, many are yet to be discovered. During the last few decades, scientists have searched for these genes with genome-wide linkage and association methods, and with more targeted candidate gene studies.
Mitochondrial 'bottleneck' cracked
Scientists have shown for the first time how a particular family of diseases are passed down from mother to child and how this can lead to the severity of the disease differing widely. The research, funded by the Wellcome Trust, offers hope of being able to predict a child's risk of developing a mitochondrial disease which can cause muscle weakness, diabetes, strokes, heart failure and epilepsy.
Life-threatening gene defect located by UT-Houston researchers
A research team led by scientists at The University of Texas Medical School at Houston has identified a defective gene that affects vascular smooth-muscle cells in people who suffer from hereditary thoracic aortic disease, which can kill victims with little warning in the prime of their lives.
OHSU researchers identify master switch that regulates blood pressure
A team of Oregon Health & Science University researchers studying a rare form of hypertension has identified the mechanism by which they believe a protein complex in the kidney operates as a master switch that regulates blood pressure, a finding that has broad implications for the treatment of more common forms of hypertension.
The importance of gene regulation for common human disease
A new study published in
Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.
Scientists identify first gene linked to scoliosis
Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery -- until now. For the first time, researchers have discovered a gene that underlies the condition, which affects about 3 percent of all children.
