Abstract

Results Following quality control, 975,508 single nucleotide polymorphisms in 2,241 cases (discovery 1,102; replication 1,133) and 776 controls (discovery 405, replication 371) remained. Genotype imputation resulted in 9,077,347 single nucleotide polymorphisms and insertions/deletions with minor allele frequency greater than 0.01 available for analysis. Meta-analysis of the discovery and replication samples identified 6 loci on chromosomes 5, 10, 11, 12 and 18 associated with urgency urinary incontinence at p <10-6. Of the loci 3 were within genes, the zinc finger protein 521 (ZFP521) gene on chromosome 18q11, the ADAMTS16 gene on chromosome 5p15 and the CIT gene on chromosome 12q24. The other 3 loci were intergenic. Conclusions Although environmental factors also likely contribute, this first exploratory genome-wide association study for urgency urinary incontinence suggests that genetic variants in the ZFP521, CIT and ADAMTS16 genes might account for some of the observed heritability of the condition.
