Gene rated Green : From feedback from Genomics England Clinical team (Anna de Burca). Although Extension of panel scope - syndrome with non-neurological features / Broader phenotype - cerebrotendinous xanthomatosis, it was noted that it was good to pick up early so advised Green rating over Amber for R57 panelCreated: 6 Dec 2019, 3:40 p.m. | Last Modified: 6 Dec 2019, 4:19 p.m.
Panel Version: 0.48
Comment on list classification: This gene has changed ratings because the panel for R78 was going to be a broad panel (to include conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation eg. HSP) but subsequently during the follow up call on 21st June with the Test Group it was agreed that it was more clinically relevant for R78 to be restricted to genes that are associated with isolated neuropathy, which this panel represents. For genes that represent the broader phenotype see https://panelapp.genomicsengland.co.uk/panels/85/.Created: 6 Dec 2019, 3:38 p.m. | Last Modified: 6 Dec 2019, 3:38 p.m.
