Genotype–phenotype analysis stratified time-to-event analysis for the most common variant (p.Arg249Trp) against all other variants. (A) Visual analysis of the curve for loss of ambulation suggests that half of individuals lose ambulation by five years of age for patients with the p.Arg249Trp variant. (B) A similar difference is shown for time to NIV (non-invasive ventilation) (n = 12 p.Arg249Trp, n = 29 other variants). (C) No difference is noted for time to first rhythm abnormality (n = 12 p.Arg249Trp, n = 11 other variants).
