As discussed with the GMS Neurology Specialist Test Group webex call 26th July 2019: The Specialist Test Group all agreed that there is only enough evidence to rate this gene RedCreated: 1 Aug 2019, 3:43 p.m. | Last Modified: 1 Aug 2019, 3:43 p.m.
Panel Version: 1.188
New gene added by Wessex and West Midlands GLH and London North GLH. Gene and Green rating to be discussed by the Neurology Test Group in July 2019 - since this relates to repeat STR entity and not a gene entity. BEAN1 STR has not yet been validated by the pipeline.Created: 19 Jun 2019, 12:11 p.m.
