CAH2_HUMAN Defects in CA2 are the cause of osteopetrosis autosomal recessive type 3 (OPTB3) [MIM:259730; also known as osteopetrosis with renal tubular acidosis, carbonic anhydrase II deficiency syndrome, Guibaud-Vainsel syndrome or marble brain disease.

The disorder occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts. OPTB3 is associated with renal tubular acidosis, cerebral calcification (marble brain disease) and in some cases with mental retardation.[1] [2] [3] [4] [5]

Publication Abstract from PubMed
Several aromatic/heterocyclic sulfonamide scaffolds have been used to synthesize compounds incorporating NO-donating moieties of the nitrate ester type, which have been investigated for the inhibition of five physiologically relevant human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms: hCA I (offtarget), II, IV and XII (antiglaucoma targets) and IX (antitumor target). Some of the new compounds showed effective in vitro inhibition of the target isoforms involved in glaucoma, and the X-ray crystal structure of one of them revealed factors associated with the marked inhibitory activity.
