Summary

Vesicoureteric reflux (VUR) is a congenital defect with a genetic basis. Some VUR-related kidney damage may stem from congenital malformations, not solely reflux, suggesting shared genetic causes.

Area of Science:

  • Urology
  • Genetics
  • Developmental Biology

Background:

  • Vesicoureteric reflux (VUR) is a congenital urinary tract defect affecting up to 1% of the population.
  • VUR is linked to recurrent urinary tract infections and renal failure, with no decrease in end-stage renal disease incidence despite treatment.
  • Twin and family studies indicate a significant genetic component to VUR.

Purpose of the Study:

  • To investigate the genetic underpinnings of VUR.
  • To explore the relationship between VUR, congenital kidney malformations, and renal failure.
  • To identify genetic factors influencing ureteric budding and kidney development.

Main Methods:

  • Analysis of human and mouse genetic data.
  • Review of twin and family studies on VUR.

  • Examination of gene candidates regulating ureteric budding.

    • Main Results:

    • VUR has a demonstrable genetic basis.
    • Identified gene candidates are involved in ureteric budding during kidney and urinary tract development.
    • Evidence suggests some renal damage in VUR cases is congenital, arising from kidney malformations.

    Conclusions:

    • The genetic basis of VUR may involve defects affecting both kidney and urinary tract formation.
    • Congenital kidney malformations could contribute to renal damage in VUR patients.
    • Shared genetic factors may underlie the co-occurrence of VUR and renal failure.
