MGI Phenotype

Strain: 3759448; 3043127
Lethality: D1
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene belongs to the ROBO family, part of the immunoglobulin superfamily of proteins that are highly conserved from fly to human. The encoded protein is a transmembrane receptor for the slit homolog 2 protein and functions in axon guidance and cell migration. Mutations in this gene are associated with vesicoureteral reflux, characterized by the backward flow of urine from the bladder into the ureters or the kidney. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]
PHENOTYPE: Homozygous mutants display postnatal lethality, abnormal ureteric bud development, multiple fused kidneys, multiple ureters, and abnormal commissural axon growth. [provided by MGI curators]
