Red List (low evidence)

Comment on list classification: Demoted STR from Green to Red based on GLH review and a recent comment (September 30th 2019) from Robyn Labrum (University College London Hospitals) collated on behalf of London North GLH for the GMS Neurology specialist test group: Inappropriate phenotype. Better suited to ataxia panels, epilepsy or muscular dystrophy panel.

Review and rating from Robyn Labrum (University College London Hospitals) was collated (September 19th 2019) on behalf of London North GLH for the GMS Neurology specialist test group for clinical indication R66: Paroxysmal central nervous system disorders. Symbol submitted: ATN1_CAG. Suggested rating: ?; Comments provided: Triplet repeat. Primarily an ataxia gene. Also ataxia is not episodic/paroxysmal in nature.
