Frequently Asked Questions
Not exactly. A genetic marker is often a piece of DNA located near or within a gene, used as a signpost to track the inheritance of that gene or region.
Typically no. It is an identifiable variation used as a tool. It may be associated with a disease-causing gene if it is located very close to it.
Most commonly encountered in direct-to-consumer genetic ancestry tests and some medical diagnostic tests that screen for genetic predispositions.
A genetic marker refers specifically to DNA-level variations. A biomarker is a broader term for any measurable biological indicator, which can be genetic, chemical, or physiological.
A gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species.
Genetic marker is usually formal, technical in register.
