In genetics, a biomarker (identified as genetic marker) is a DNA sequence that causes disease or is associated with susceptibility to disease. They can be used to create genetic maps of whatever organism is being studied.ne example of a commonly used biomarker in medicine is prostate-specific antigen (PSA). This marker can be measured as a proxy of prostate size with rapid changes potentially indicating cancer.
1 Genetic = The length of DNA of the gene responsible for a trait has been identified and its sequence determined. 2  Genetic = the gene responsible for a trait has been sequenced, and we know the molecular biology of how the gene product works and how mutations in it produce different results.n allele represents one or more DNA sequences in a gene that produces a particular phenotypic result. Several different mutations might cause a gene to produce a defective protein. All of these mutations might be lumped into a single allele-the gene in a form that produces a defective protein.
