La secuenciación del exoma de 124 tríos de niños fallecidos por muerte súbita y ambos padres, condujo a identificar mutaciones de novo en genes asociados a funciones cardiacas o neurológicas. El reporte aparece en Halvorsen M, Gould L, Wang X, Grant G, Moya R, Rabin R, et al. De novo mutations in childhood cases of sudden unexplained death that disrupt intracellular Ca2+ regulation. PNAS December 28, 2021;118(52):e2115140118.
