Tania Attié-Bitach and colleagues report that biallelic mutations in KIF7, a component of the Hedgehog signaling pathway, cause hydrolethalus and acrocallosal syndromes. They also present evidence that heterozygous KIF7 mutations contribute to the allelic load and phenotypic spectrum of other cilia disorders.
