Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia—abnormal blood cholesterol levels that can contribute to heart disease. Study details published in the February issue of Hepatology, a journal of the American Association for the Study of Liver Diseases (AASLD), describe a new in silico approach to identify the significance of microRNAs in regulating disease-related gene pathways. http://medicalxpress.com/news/2013-02-liver-gene-cholesterol-fat-blood.html Genetics Thu, 07 Feb 2013 14:49:29 EST news279470963 Using only a computer, an Internet connection, and publicly accessible online resources, a team of Whitehead Institute researchers has been able to identify nearly 50 individuals who had submitted personal genetic material as participants in genomic studies. http://medicalxpress.com/news/2013-01-expose-vulnerabilities-personal-genetic.html Genetics Thu, 17 Jan 2013 14:00:31 EST news277652517 Scientists have adopted a novel laboratory approach for determining the effect of genetic variation on the efficiency of the biological process that translates a gene's DNA sequence into a protein, such as hemoglobin, according to a presentation, Nov. 6, at the American Society of Human Genetics 2012 meeting in San Francisco. http://medicalxpress.com/news/2012-11-method-link-genomic-variation-protein.html Genetics Tue, 06 Nov 2012 19:30:01 EST news271440596 Scientists have completed a comprehensive map of genetic mutations linked to an aggressive and lethal type of lung cancer. http://medicalxpress.com/news/2012-09-genome-wide-scan-mutations-deadly-lung.html Genetics Wed, 05 Sep 2012 15:34:11 EST news266078042 Hispanic children are more likely than those from other racial and ethnic backgrounds to be diagnosed with acute lymphoblastic leukemia (ALL) and are more likely to die of their disease.

The finding may help determine which patients are likely to benefit most from implantable cardio-defibrillators (ICDs). http://medicalxpress.com/news/2011-05-gene-variant-sudden-cardiac-death.html Genetics Wed, 11 May 2011 08:01:28 EST news224319514
