Genes affected

ROBO2 (HGNC:10250): (roundabout guidance receptor 2) 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]

The ROBO2 c.41C>G variant is predicted to result in the amino acid substitution p.Thr14Arg. This variant corresponds to a precoding position in the primary transcript for this gene (NM_002942.4:c.-1103252C>G). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.040% of alleles in individuals of African descent in gnomAD; However, the quality of data at this position is questionable and should be interpreted with caution. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
