A rare genetic immunodeficiency due to a complement cascade protein anomaly characterised by low or undetectable serum ficolin 3 levels, susceptibility to infections and possibly autoimmunity.

A rare genetic intellectual disability syndrome with characteristics of severe global developmental delay with intellectual disability, microcephaly, growth retardation, ocular defects such as congenital cataract and naevus flammeus simplex on the forehead. Cardiac, urogenital, and skeletal abnormalities, as well as seizures are present in most patients.
