Genetic epilepsy syndromesGene: PEX13
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.

AR Perioxisome biogenesis disorder 11A and 11B. 11A - Al Dirbashi et al, 2009 - studied 2 unrelated Saudi patients - children of consang parents with Zellweger syndrome - both children had seizures alongside other features of Zellweger and died young. One patient had a hom deletion encompassing entire PEX3 gene and the other had a hom smaller out of frame del. Shimozawa et al - patient with severe Zellweger phenotype - hom nonsense variant. 11B - milder manifestion of type 11A.
