*** A rare genetic deficiency.

The rare genetic deficiency of C1 esterase inhibitor (an enzyme which controls the functioning of C1 esterase) results in hereditary angiodæma. Lack of this enzyme causes inappropriate activation of C2 and the production of large quantities of C2a (also known as C2 kinin). This is a potent inducer of inflammation and of vasodilatation. The vasodilatation results in the oedema.
