Early onset or syndromic epilepsy
Gene: PEX7
As discussed with members of the GMS Neurology Specialist Test Group on the Webex call 22nd November 2019 for Clinical Indication R59 Early onset or syndromic epilepsy: Agreed that there is insufficient evidence to rate this gene Green. Better tested through the metabolic panel. Demoted from Green to Amber.Created: 25 Nov 2019, 8:59 p.m. | Last Modified: 25 Nov 2019, 8:59 p.m.

AR Perioxisome biogenesis disorder 9B and Rhizomleic chondroplasia punctata type 1. PBD9B - milder phenotype with long survival less neurologic involvement, normal or near growth and absence of rhizomelia. RCDP1 - characterised by disprop short stature primarily affecting the proximal parts of the extremities and other features. Most die in first decade of life - can't see any mention in the clinical features section on OMIM of seizures/epilepsy.Created: 6 Aug 2019, 8:31 p.m. | Last Modified: 6 Aug 2019, 8:31 p.m.

Comment when marking as ready: Associated with relevant phenotype in OMIM and as confirmed Gen2Phen gene. Seizures are a part of the spectrum of features in this phenotype (Genomics England clinical fellow Arianna Tucci).At least 6 variants reported in at least 7 cases.Created: 7 Nov 2018, 5:07 p.m.
