Genomic Unity® Dementia Analysis

Test Description

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.

When to order

Order this test when clinical symptoms are consistent with dementia. You also have the option to reflex up to Genomic Unity® Exome Analysis or Genomic Unity® Exome Plus Analysis if targeted analysis is non-diagnostic.

Included Analyses

  • 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)

Optionally includes:

Included Genes


This test covers many disorders including:

  • Alzheimer Disease
  • Frontotemporal Dementia

Specificity for SNVs
Positive predictive value for SNVs
Clinical sensitivity for structural variants

Short tandem repeats:

Due to the variable nature of repetitive sequences and sequence-specific differences in detection and repeat evaluation, orthogonal confirmation is performed on a case-by-case basis. Reportable pathogenic or intermediate repeat expansions may be reported with or without repeat count.
