TNNI3 and cardiomyopathy: In subgroup analysis of 42 patients with both hs‐cTnI and hs‐cTnT results and a contemporaneous cMRI, there was no significant difference between FRTnT and FRTnI distributions in FD patients with cardiomyopathy (n = 21, p = 0.375) and similarly no significant difference between FRTnT and FRTnI distributions in FD patients without cardiomyopathy (n = 20, p = 0.936).
