ADmark® is a specialized clinical genetic test designed for the evaluation of Early Onset Alzheimer's disease. It serves as a tool within the medical field to assess genetic factors related to the development of Alzheimer's disease that manifests at a younger age.
Purpose of ADmark Evaluation
The primary purpose of the ADmark evaluation is to identify specific genetic variations that are known to be associated with early-onset forms of Alzheimer's disease. Unlike the more common late-onset Alzheimer's, which typically develops after age 65, early-onset Alzheimer's can affect individuals in their 30s, 40s, or 50s.
This genetic test is particularly relevant for:
- Individuals exhibiting early symptoms suggestive of Alzheimer's disease.
- People with a strong family history of early-onset Alzheimer's, where a genetic predisposition is suspected.
- Differential diagnosis, helping clinicians distinguish Alzheimer's from other conditions with similar symptoms.
The evaluation provides crucial information that can assist healthcare providers in making informed decisions regarding diagnosis, patient management, and counseling for individuals and their families.
Understanding ADmark as a Clinical Genetic Test
As a clinical genetic test, ADmark involves analyzing a person's DNA to look for specific mutations or variations in genes known to play a role in early-onset Alzheimer's disease. These genes, when mutated, can directly cause the disease or significantly increase an individual's risk.
Typically, such tests focus on genes like:
- Amyloid Precursor Protein (APP): Mutations in this gene can lead to the overproduction of amyloid-beta, a protein fragment that accumulates in the brain to form plaques characteristic of Alzheimer's.
- Presenilin 1 (PSEN1): Mutations in PSEN1 are the most common cause of early-onset familial Alzheimer's disease.
- Presenilin 2 (PSEN2): While less common than PSEN1 mutations, variations in PSEN2 can also lead to early-onset Alzheimer's.
These genes are fundamental to the production and processing of amyloid-beta proteins. Detecting mutations in these genes can confirm a genetic cause for early-onset Alzheimer's disease.
Key Aspects of ADmark
