The emergence of novel cardiac biomarkers Gal‐3 and ST2 could now provide the opportunity to explore which athletes may be most at risk of experiencing sudden cardiac death (SCD), since cardiac fibrosis could contributed to the development of SCD and Gal‐3 and ST2 could give additional information compared with other well‐established biomarkers. Here, LGALS3 is linked to Schnyder corneal dystrophy.
