We also assessed relationships between the most clinically relevant measures of LV rotational mechanics (apical rotation, basal rotation, net twist, and torsion) and Hb (n = 216), B-type natriuretic peptide (n = 106), and lactate dehydrogenase (n = 199), in patients with SCD only, but none were significant (data not shown). Here, GSTM1 is linked to Schnyder corneal dystrophy.
