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. Re-review of a subset of genes was conducted in September 2019 to reach a rating consensus for clinical indication R66: Paroxysmal central nervous system disorders. Suggested rating: Red.
