genetic marker

n.
A gene, DNA sequence, or gene product whose inheritance can be traced through a pedigree or phylogeny. Genetic markers are used in paternity testing, studies of evolution, and evaluating genetic contributions to phenotypes including disease. Genetic markers associated with certain diseases can often be detected in the blood serum, where their presence is used to determine whether a person is at high risk for developing a disease.

genetic marker

n
(Genetics) a gene with two or more alternative forms, producing readily identifiable variations in a particular character, used in studies of linkage, genetic mapping, and identification of the presence of other genes that are closely linked to, and therefore usually inherited with, it

genet′ic mark′er


n.
any gene or allele that is associated with a specific chromosome and can be used to identify the chromosome or to locate other genes or alleles. Also called marker , marker gene.

These two databases use completely different systems of genetic markers. The investigators report in a proof of principle with 872 people that for close relatives -- either sibling or parent-offspring pairs -- more than 30% can be accurately matched with the correct relative using nonoverlapping genetic markers from the two different databases.
Premier and Progknowse plan to work with leading research universities and data scientists to develop real-time predictive algorithms that can be used by individual health systems to support care interventions for patients with specific genetic markers. Progknowse will utilize the PremierConnect platform to access national data sets that include de-identified clinical outcomes data on approximately 45% of all patient discharges in the U.S.
In the future, a predictive test for the condition could become available thanks to a breakthrough by Australian researchers, who have identified certain genetic markers that increase the risk of developing the disease.
