Importantly, GWASs in inherited cardiac disorders have revealed several novel risk loci, such as HEY2 (OMIM: 604674) for BrS, NOS1AP (OMIM: 605551) for LQTS, and FHOD3 (OMIM: 609691) for HCM, revealing critical information about the biological pathways driving these disorders, as discussed in more detail in the following section. The gene discussed is NOS1AP; the disease is familial long QT syndrome.
