DS was significantly associated with increased DNAmAA (effect estimate = 0.2406, p < 0.0001) (Table 2); the associations remained after excluding the high nRBC newborns (effect estimate = 0.1282, p < 0.0001) and when limited to GATA1‐wildtype DS newborns (effect estimate = 0.1735, p < 0.0001). The gene discussed is GATA1; the disease is Dravet syndrome.
