In the original publication of this article [1], a numerical value in the sentence “The mean (SD) AAO was 43.92 years (9.24) for all subjects, with a significant difference between patients carrying mutations in exon 2 (n = 24, 46.83, 8.31) and exon 4 (n = 18, 37.75, 7.67) (p = 0.002).” is wrong. The true value in the parenthesis of exon 2 should be (n = 24, 46.63, 8.31).
