Other relevant cardiac loci include desmoglein 2 (DSG2) (Kant et al., 2015), desmoplakin (DSP) (Smith and Fuchs, 1998; Gigli et al., 2019), and titin (TTN) (Herman et al., 2012; LeWinter and Granzier, 2013) identified in both severity and PASC cohorts, and myosin heavy chain 7 (MYH7), identified exclusively in the PASC cohort (Hinton et al., 2010; Yotti et al., 2019; Ritter et al., 2022). Here, TTN is linked to long COVID-19.
