Panel Version: 1.95
Comment on list classification: This STR has been removed at the request of GHLs for the GMS Neurology Specialist Test Group as it is available as a core test for R68 Huntington Disease. Inclusion on panels for other neurological CIs raises concerns regarding counselling, and so it has been agreed that HTT_CAG will be excluded from this panel.Created: 6 Oct 2020, 10:39 a.m. | Last Modified: 6 Oct 2020, 10:39 a.m.
