  • c = carrier females, nc = non-carrier females. All males are affected.

  • Classification method: B = genetic loci determined by both heterogeneity analysis and haplotype analysis; HA = genetic loci determined by haplotype analysis only; HE = genetic loci determined by hetergeneity analysis only.

  • ERG indicates early electrodiagnostic testing.
