MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase-like protein. Mutations in this gene are the cause of Walker-Warburg syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2012]
PHENOTYPE: Mice homozygous for an ENU-induced allele exhibit neonatal lethality due to respiratory failure, abnormal axon guidance and fasciculation, abnormal dorsal funiculus, detachment of radial glial cell endfeet and neuronal heterotopias. [provided by MGI curators]
