Genomic Unity® Dementia Analysis
Test Code – NR010
Dementia is characterized by a decline in cognitive function – such as thinking, reasoning, personality, and memory – that impact daily life. The two most common causes of hereditary dementia are Alzheimer disease (AD) and frontotemporal dementia (FTD).
Genomic Unity® Dementia Analysis uses a whole genome sequencing platform to diagnose genetic causes of dementia in 33 genes.
- Sequence analysis of dementia-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
- Copy number variant analysis of dementia-associated genes (duplications/deletions, mobile element insertions, and inversions)
- Short tandem repeat (STR) analysis of FTD and/or Amyotrophic lateral sclerosis (ALS)-associated gene: C9orf72
- Risk for late onset of AD (APOE status)
Note: The GBA gene is not fully covered by this test, therefore not all pathogenic variants may be detected. The APOE genotype is provided for informational purposes only. No interpretation regarding risks associated with this gene are reported. Short tandem repeats are not reported in the PRNP gene.
This test covers many disorders including:
- Alzheimer Disease
- Frontotemporal Dementia
- Hereditary diffuse leukoencephalopathy
- Lewy body dementia
