-
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. The presentation is variable, from perinatal necrotising enterocolitis and recurrent skin infections with Staphylococcus aureus to childhood-onset recurrent pulmonary infections leading to brain abscesses and pulmonary fibrosis, to membranous nephropathy. In some patients clinical consequences of ficolin 3 deficiency were not clear. There is evidence that ficolin 3 deficiency is caused by homozygous mutation in the FCN3 gene on chromosome 1p36.
