Primary immunodeficiency or monogenic inflammatory bowel disease

Gene: RAB27A

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.
