I don't know

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 PEX genes are better tested through the metabolic panel, and should be demoted to Amber.

Green List (high evidence)

AR Perioxisome biogenesis disorder 4A, AD and AR 4B and Heimler syndrome 2. 4A - Fukuda et al, 1996 - Japanese girl - non consang parents - clonic seizures in the neonatal period - death at 7 months - PEX6 variants identifed. 4B milder manifestation of Zellweger syndrome - no mention of seizures in any of the patients described on OMIM - functional studies on the R860W variant undertaken. Heimler syndrome 2 - mildest end of the sprectrum with sensorineural hearing loss, enamel hypoplasia of the secondary dentition and nail abnormalities - seizures not a feature.
