Eleanor Williams (Genomics England Curator)

Comment on list classification: Changed rating of gene from Red to Green. This gene was rated as Green in v2.208 and incorrectly automatically demoted to Red in v2.209. This was due to a defect in the automatic PanelApp uploading tool when a set of publications was added to the panel with the source ‘Other’, and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been.

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.

2018-07-12 Louise Daugherty (Genomics England Curator) promoted panel to v1.0. Reviews were assessed, and panel was revised according to expert reviews and further in-house curation based on PanelApp guidelines. Previous panels (A- or hypo-gammaglobulinaemia, Congenital neutropaenia, Agranulocytosis, Combined B and T cell defect, Inherited complement deficiency and SCID panels) that were merged with this panel, were checked again for any changes/new reviews prior to versioning of this panel, these merged panels are now retired/made internal.
