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.

CAR3 is decreased by 0.76 percentage points when MH1 changes from zero to one as compared to the sample mean of 0.3%.
Taking Model 6 as another example, the coefficient on MH2 indicates that an increase in MH2 by one standard deviation (2.21) is expected to decrease CAR3 by 0.26 percentage points.
