Median age at DCM onset by SPP1 and LTBP4 genotype.

*Significant difference between genotypes (log-rank p§DCM onset was observed in less than 50% of patients, so no median value can be calculated.Total n for LTBP4 differs due to limited DNA availability in a few patients. For SPP1, patients included in the previous report about loss of ambulation (Pegoraro et al, 2011) were also excluded. SPP1: Secreted PhosphoProtein 1. LTBP4: latent transforming growth factor beta binding protein 4. DCM: dilated cardiomyopathy.Median age at DCM onset by SPP1 and LTBP4 genotype.
