Correction to: Genetics in Medicine https://doi.org/10.1038/gim.2017.35; published online 27 April 2017
Since the online publication of the article, the authors have noted errors with Table 2. Patient 8 in Table 2 should be replaced by patient 16, patient 9 should be patient 17, patient 10 should be patient 18, patient 11 should be patient 19, patient 12 should be patient 20, and patient 15 should be patient 22, to correspond to the patient numbers in the full patient table with mutation data in Supplementary file 1 online. Also in Table 2, the correct reference for patients D and E is 31, not 30 as stated. The authors apologize for any inconvenience caused by these errors.
