NCIt definition : Human HTR2A wild-type allele is located within 13q14-q21 and is approximately 63 kb
in length. This allele, which encodes 5-hydroxytryptamine 2A receptor protein, is
involved in several processes that activate a PI-calcium second messenger system via
G-protein association, such as tracheal smooth muscle contraction, bronchoconstriction,
and control of aldosterone production.;
