Overview

Mannose-binding lectin protein (MBL) deficiency is a complement component deficiency that alters the function of the body's immune system. This condition usually causes frequent and sometimes severe infections in infants and young children.[1] This deficiency can occur as a result of one or more variations in the MBL2 gene, which codes for the MBL protein. A lack of this protein can cause this condition, but is likely further influenced by other genetic and environmental factors.[2]
