CA.1ad.3

A gene on chromosome 8q21.2 that encodes a carbonic anhydrase, a zinc metalloenzyme that catalyses the reversible hydration of carbon dioxide. Carbonic anhydrases participate in various biological processes, including respiration, calcification, maintaining acid-base balance and bone resorption, as well as producing aqueous humour, cerebrospinal fluid, saliva and gastric acid. Carbonic anhydrase 3 is a glycosylphosphatidyl-inositol-anchored membrane isozyme, expressed on the luminal surfaces of pulmonary (and other) capillaries and proximal renal tubules; it is thought to have a role in hereditary defects in bicarbonate transport.

Damage can occur with much less exposure to acid, (1) not only because of the decrease in CAIII, but also because of the absence of peristalsis in the larynx.
