Green List (high evidence)

Eight individuals harboring heterozygous IKZF1R183H or IKZF1R183C variants associated with GOF effects. The clinical phenotypes and pathophysiology associated with IKZF1R183H/C differ from those of previously reported patients with IKZF1HI, IKZF1DN, and IKZF1DD and should therefore be considered as a novel IKAROS-associated disease entity. This condition is characterized by immune dysregulation manifestations including inflammation, autoimmunity, atopy, and polyclonal PC proliferation.

Over 25 individuals from 9 unrelated families with variants in IKZF1 displaying Immunodeficiency; three mouse models Heterozygous missense, frameshift and deletion variants in IKZF1 gene resulting in loss or alteration of a zinc finger DNA contact site cause LoF. Typically presents with recurrent bacterial respiratory infections, hypogammaglobulinaemia and low Ig levels; variable age of onset.
