  1. *Serum iron, ferritin, iron binding capacity, and transferring saturation were available for n = 541, n = 546, n = 542, and n = 540 subjects, respectively.
  2. **An allele dose of 2+ includes all that were homozygous for C282Y, homozygous for H63D, and compound heterozygous for both C282Y and H63D.
