Reviewed again and decided to keep as Amber, there are some conflict regarding the pertinence, still only two cases reported in the literature, and in addition to this, in Clinvar (July 2017) there are conflicting interpretations of pathogenicity reported in some clinical labs worldwide: Likely benign (Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine and ARUP Laboratories, Molecular Genetics and Genomics);Uncertain significance (Invitae), the gene-disease is not that strong.

This gene was present in the original PanelApp PID panel dataset (review in April 2018) rated as Red. The gene is present in the 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.
