HIF3A and hydrops fetalis: We identified the down-regulation of HIF3A for dilated cardiomyopathy, SCN7A (Sodium Voltage-Gated Channel Alpha Subunit 7, 182392) for hypertrophic cardiomyopathy, MALAT1 (Metastasis Associated Lung Adenocarcinoma Transcript 1) up-regulation for HF-hypoplastic left heart syndrome, and down-regulation for neo-hypoplastic left heart syndrome, which have been confirmed by previous publications [99,100,101].
