Ift172 encodes a gene product that is part of a complex that mediates intraflagellar transport (IFT), a process necessary for the genesis and maintenance of cilia. Genetic studies in mice have offered evidence that Ift172 also plays a role in hedgehog signaling. Disruption of Ift172 in mice is associated with lethality at about embryonic day 11, limiting studies to understand the role for Ift172 in later development and the adult. To further our understanding of the later roles of Ift172, we have generated mice with a conditional allele for Ift172. We have confirmed the phenotype of the disrupted allele by using CRE expression directed by the prx1 enhancer to disrupt the conditional Ift172 allele in the developing limb.
