Correction to: Genetics in Medicine https://doi.org/10.1038/s41436-018-0269-0; published online 7 September 2018

Corrections were made to the footnotes in Table 2.

The authors originally provided superscript “*” and “**” to reflect the statistical significance; these footnotes were mistakenly changed into “a” and “b” by the production team at the proof stage. However, because “a” and “b” were already assigned in the originally submitted Table 2 with a different meaning (i.e. “a” meaning “based on data from this study and Upadhyaya et al.4” “b” meaning “based on data from Pinna et al.5, Rojueangnit et al.6, Ekvall et al.8, Nystrom et al.9 and Santoro et al.10”), this mistake in the proofs was communicated to the production team and the corresponding author requested to revert to the correct footnotes as originally submitted for Table 2. Production team thereafter however changed only a single value into “*“, leaving the remaining “a” and “b” unchanged and published as such on 7 September 2018 online. The corresponding author informed the production team the same day that their changes did not yet correct their initial mistakes and made the interpretation of Table 2 impossible for the reader. The production team acknowledged their mistakes and replaced footnotes for statistical relevance by “o” and “p” and the placement of the paragraph on statistical significance in the legend was changed too, so that “o” and “p” came after “n”.
