Genomic Unity® Epilepsy Analysis
Test Code – NR004
Epilepsy is a result of abnormal brain activity leading to seizures, which can have a wide range of presentations. These episodes may include uncontrolled twitching of arms and legs, staring into space, loss of attention, confusion, loss of consciousness or awareness, sudden feelings of fear or anxiety, and complaints of unusual sensations such as sights, sounds, tastes, smells, and feelings. Importantly, seizures are not always easily recognizable, particularly in young children.
Genomic Unity® Epilepsy Analysis uses a whole genome sequencing platform to diagnose genetic causes of epilepsy, with or without other symptoms, in 378 genes.
When to order
Order this test when clinical symptoms are consistent with seizures. 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.
- Sequence analysis of seizure-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants).
- Copy number variant analysis of seizure-associated genes (duplications/deletions, mobile element insertions, and inversions).
- Short tandem repeat (STR) analysis of the AFF2, CSTB, DIP2B, and FMR1 genes.
This test covers many disorders including:
- Generalized epilepsies
- Focal epilepsies
- Epileptic encephalopathies
- Familial febrile seizures
- Neuronal ceroid lipofuscinosis syndromes
- Nuclear mitochondrial complex deficiencies
- Congenital disorders of glycosylation
- Fragile X syndrome
- Rett and Rett-like syndromes
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.
