Green List (high evidence)

Comment when marking as ready: As discussed in the GMS Gastrohepatology Specialist Test Group webex call 14th Jan 2019: The Specialist Test Group agreed that there is enough evidence to rate this gene green based on unpublished data from patient cohort from USA (2,000 patients at Emory) that this is one of the Zellweger genes with significant prevalence.

Initial gene list and info collated by Miranda Durkie Sheffield Diagnostic Genetics Service December 2018 on behalf of the GMS Gastrohepatology specialist test group. Gene Symbol submitted: PEX1; Suggested intial gene rating: Green; Evidence for inclusion: none given; Evidence for exclusion: none given; Technical notes (e.g. non-coding/CNV mutations requiring coverage?): none given
