Correction to: Classical galactosemia: neuropsychological and psychosocial functioning beyond intellectual abilities.

An amendment to this paper has been published and can be accessed via the original article.

Correction to: Orphanet Journal of Rare Diseases (2020) 15:42

Following the original article’s publication [1] the authors informed us of the following errors:

1. Author M. Estela Rubio Gozalbo’s first and last names were captured incorrectly. The author’s first names are M. Estela, while last names are Rubio Gozalbo.

The correct author’s name has been updated in the original article [1] and shown in the author list of this Correction.

2. In Table 2 ‘Digit span’ and ‘GIT-2’ are tests and should be preceded by a - just like the other tests in the table.

Data reported in T-scores, median (ranges). a Patient data vs. normative data (T-score 50), b Comparison between FSIQ groups, Significant after Bonferroni-Holm correction. FSIQ full scale IQ, AVLT auditory verbal learning test, GIT-II groninger intelligentie test 2, Stroop stroop color word test, WCST wisconsin card sorting test, TMT trail making test

Furthermore, ‘Responses’ is not a domain and should therefore be deleted.

Finally, ‘Cconceptual’ should be corrected to ‘conceptual’.

The table is shown here corrected.

3. The grey box for ‘test result better than expected’ is missing from the legends of Tables 4 and 5.

The two tables with their respective legends are shown here corrected.

4. In Table S8 of the Additional file 1, some rows have shifted. ‘Anxiety & Depression’ and ‘Social Functioning’ should be shown on separate lines. HADS should be in line with ‘Anxiety & Depression’ and SRS with ‘Social Functioning’.

In addition, subsequent references should be renumbered as 35–49.

The corrected Additional file 1 accompanies this Correction.
