External expert review notes Amber status, but as it is not Mendelian disorder I have kept this gene Red on this panel until further evidence to support upgrading the status

Comment on list classification: Changed from Amber to Red. This gene was only found in the v2.0 GRID dataset, but there is no current evidence in the literature to support the pertinence of this gene and immunity yet. GRID team confirm this gene will be removed/downgraded from Tier1 in their next iteration of the GRID panel- so agree it should be Red and not Amber

Although CFHR2 is part of the complement system there is not enough evidence currently to support variants of this gene being linked to a immunity disorder. In addition to this, GRID will be removing CFHR2 as a Tier 1 gene from their panel after clincial input that there is no known pertinent PID disorder linked to this gene yet (pers comm Karyn Megy)

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.

Pers. comm with Karyn Megy, WGS Clinical Feedback Lead that this gene is not pertinent, and will be removed from the GRID panel
