ORPHA:331190Disease
What it is
Immunodeficiency due to ficolin3 deficiency is a rare, genetic, immunodeficiency due to a complement cascade protein anomaly characterized by low or undetectable serum ficolin3 levels, susceptibility to infections, and possibly autoimmunity. The presentation is variable, from perinatal necrotizing 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 ficolin3 deficiency were not clear.

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
