The genetics of incontinence: A scoping review

Publikation: Bidrag til tidsskrift/Konferencebidrag i tidsskrift /Bidrag til avisReviewForskningpeer review


The genetic causes underlying incontinence in both children and adults have begun to be unravelled during the last decades. The aim of this scoping review is to synthesize current knowledge on the genetics of childhood and adult urinary and faecal incontinence, identify similarities between different incontinence subgroups, and identify knowledge gaps to aid future research. PRISMA-ScR was used, and 76 studies were included. Early epidemiological family and twin studies suggest high heritability of incontinence. Linkage studies provide evidence for the existence of rare genetic variants; however, these variants have not been identified. Later candidate gene association studies and recent genome-wide association studies provide the first preliminary evidence that common risk variants also play a role. The genetics of incontinence in children and adults has predominantly been studied separately, but this review identifies for the first time the endothelin system as a potential common pathophysiological pathway. Overall, these findings strengthen the hypothesis that genetic variants play a prominent role in the pathogenesis of incontinence. Future research should include hypothesis-free studies of rare and common variants in large well-characterized cohorts with incontinence. Studies should include different age groups and ethnicities and both sexes to fully reveal the genetics of incontinence.
