To the Editor:
The authors regret that there was an important error in the results in Table 1; the ATP7A mutations detected in Patients 2 and 14 were incorrectly noted.
The corrected notation of the mutations is as follows:
1) The c.1303delA (p.A434Qfs*2) mutation detected in Patient 2 should be changed to c.1303delA (p.Ile435*).
2) Patient 14 had a previously known mutation, i.e., c.3257delA (p.His1086Profs*3); c.4048G>A (p.E1350K) is a common single nucleotide polymorphism detected together with the mutation.
Accordingly, corrections in the main text are needed as follows:
1) In the first paragraph of “Mutational analyses of the ATP7A gene” on page 3, “2 missense mutations,” “2 frame-shifting short deletions,” and “Seven mutations were novel” should be changed to “1 missense mutation,” “3 frame-shifting short deletions nonsense mutations,” and “Six mutations were novel.”
2) The last sentence in the first paragraph of the “Discussion” section, “Patient 14 in our study had a missense mutation in ATP7A,” should be changed to “Patient 14 in our study had a frame-shifting short deletion mutation in ATP7A.”
