Genes affected

CAP1P1 (HGNC:31134): (CAP1 pseudogene 1)

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.576 is higher than 0.05.
