Correction to: European Journal of Human Genetics (2009) 17, 1560–1569; doi:10.1038/ejhg.2009.75; published online 24 June 2009

Since the publication of the above paper, the authors have identified two errors:

  • In the Discussion (p 10), Table 2 (p 9) and Supplementary Figure 6, the mutation c.404delC should be c.404delG.

  • In the pedigree depicted of family 1 there also is an error since VI: 5 is still alive.

The authors would like to apologise for these mistakes.
