Further, SCN5A human variants (usually autosomal recessive inheritance patterns) were linked to SND (Benson et al., 2003), dilated cardiomyopathy, conduction disorders (McNair et al., 2004; Freyermuth et al., 2016; Yang et al., 2017), and infant death syndrome (Denti et al., 2018). This evidence concerns the gene SCN5A and dilated cardiomyopathy.
