Genes affected
CA3-AS1 (HGNC:51657): (CA3 antisense RNA 1)
CA2 (HGNC:1373): (carbonic anhydrase 2) The protein encoded by this gene is one of several isozymes of carbonic anhydrase, which catalyzes reversible hydration of carbon dioxide. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2014]
