Definition: The class of heavy chains found in IMMUNOGLOBULIN A. They have a molecular weight of approximately 58 kDa and contain about 470 amino acid residues arranged in four domains and an oligosaccharide component bound covalently to their Fc fragment constant region.
gammopathy: coordinate IMMUNOGLOBULIN ALPHA-CHAINS (IM) with PARAPROTEINEMIAS (IM) but consider also HYPERGAMMAGLOBULINEMIA (IM) or ALPHA-CHAIN DISEASE (IM), follow text; DF: IG ALPHA CHAIN
