In dogs with cardiomyopathy, those dogs with cTnI concentrations greater than 0.20 ng/mL had significantly shorter survival times (median 112 days) than those with cTnI concentrations less than 0.20 ng/mL (median 357 days), regardless of the censoring status of dogs which were euthanized [7]. The gene discussed is TNNI3; the disease is cardiomyopathy.
