Genomic Unity® Movement Disorders Analysis
Test Description
Test Code – NR006
Movement disorders are a group of neurological conditions characterized by changes in speed, intention, or style of a person’s movements, whether voluntary or involuntary. Movement disorders can include ataxia, dystonia, chorea, myoclonus, parkinsonism, and tremors.
Genomic Unity® Movement Disorders Analysis uses a whole genome sequencing platform to diagnose genetic causes of abnormal movements, such as ataxias, choreas, tremors, dystonias, and others in 231 genes.
When to order
Order this test when clinical symptoms are consistent with impaired movement including ataxia, imbalance, gait disturbance, spasms and tremors, or other abnormal movements. 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 movement disorder-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
- Copy number variant analysis of movement disorder-associated genes (duplications/deletions, mobile element insertions, and inversions)
- Short tandem repeat (STR) analysis of: ATN1, ATXN1, ATXN2, ATXN3, ATXN7, ATXN8OS, ATXN10, CACNA1A, FMR1, FXN, HTT, JPH3, NOP56, NOTCH2NLC, PPP2R2B, TBP
Optionally includes:
Disorders
This test covers many disorders including:
- Ataxia Telangiectasia
- Coenzyme Q10 deficiency
- Dentatorubral-pallidoluysian atrophy (DRPLA)
- Dopa-responsive dystonia
- Friedreich’s ataxia
- Infantile onset ascending spastic paraplegia
- Marinesco-Sjogren syndrome
- Mitochondrial recessive ataxia syndrome
- Myoclonus-Dystonia
- Parkinson’s disease
- Primary torsion dystonia
- Spinocerebellar ataxias
- Tyrosine hydroxylase deficiency
Test Performance
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.
