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 239 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).
  • Repeat expansion analysis of the ARX, ATN1, ATXN1, ATXN2, ATXN3, ATXN7, ATXN8OS, ATXN10, CACNA1A, FGF14, FMR1, FXN, GLS, HTT, JPH3, NOP56, NOTCH2NLC, PPP2R2B, RFC1, TBP and ZFHX3 genes. (Learn more)

Included Genes

Note: The ATXN7, ARX and CAMTA1 genes are not fully covered by this test, therefore not all pathogenic variants may be detected. The false negative rate for repeat expansions has not been determined.
