Subvalvular Aortic Stenosis, also known as aortic stenosis, subvalvular, is related to discrete subaortic stenosis and ventricular septal defect. An important gene associated with Subvalvular Aortic Stenosis is SMCO1 (Single-Pass Membrane Protein With Coiled-Coil Domains 1), and among its related pathways/superpathways are Heart development and Cardiac progenitor differentiation. Affiliated tissues include heart, and related phenotype is Strongly decreased CFP-tsO45G cell surface transport.
