Comment on list classification: Changed from Amber to Green. The absence of Factor I leads to a continuous consumption of C3 due to an uncontrolled amplification of C3 cleavage, resulting in an acquired C3-deficiency state. Complete Factor I deficiency has been reported in at least 40 cases, with 16 mutations being described (PMID: 19065647, 21316765, 22710145, 24142231, 25988862 )

Hereditary deficiency of complement factor I is associated with a propensity to pyogenic infection and follows an autosomal recessive pattern of inheritance PMID:8613545

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.
