Genetic variation map may promise tailored drugs
Washington - In a major step toward one day offering gene-based customized medicine, scientists yesterday unveiled the first map of common human genetic variations — patterns of DNA differences that may help forecast people's disease risks and best treatments.
This map, created by California-based Perlegen Sciences Inc., is essentially the first chapter in the quest to identify tiny bits of genetic information, known as SNPs or "snips,'' believed key in creating gene-based medicine.
