Competing Interests

DHR is a scientific founder of Zirus, Inc., and performed genomic analysis of the insertion sites of the gene-trap vector. An external auditor at Vanderbilt University reviews DHR’s laboratory and reports are available from David Raiford, Associate Dean for Faculty Affairs, Vanderbilt Medical School. Thus, none of the authors declare competing interests with respect to gene identification or validation. This does not alter the authors’ adherence to all the PLOS ONE policies on sharing data and materials.
