I don't know

The Specialist Test Group discussed the inclusion of EDS genes on this panel and if included, what rating they should be. EDS genes are currently all rated as Amber until further discussion with EDS experts

Panel Version: 0.70
Comment on list classification: As discussed in the GMS Haematology Specialist Test Group webex call 8th March 2019; Sheffield would rate this gene as Red, Oxford would rate this gene as Green. Suggested Green rating as it is associated with mild forms of EDS. Decided to rate as Amber and marked for further discussion as to inclusion of EDS genes on this panel.

Follow up email correspondence with Patricia Bignell 13th March (webex 8.03.19 WWMGLH comments v1.doc) comment on COL1A1: We thought that this was agreed as GREEN on the call.
