In the original version of this Article the authors described a variant at the DNA level as “c.293delC.” This occurred several times in the Article as well as in the supplementary information. According to the HGVS-nomenclature recommendations (http://varnomen.hgvs.org/) it should be “c.294delC.” This has now been corrected in both the PDF and HTML versions of the Article and the supplementary information.
