Objective The angiotensin converting enzyme insertion/deletion (ACE I/D) gene polymorphism is involved in a wide range of clinical outcomes. This makes ACE I/D an important genetic marker. Updating the genetic profile of ACE I/D and raising the evidence for its role in renal disease is therefore needed. Reported associations of ACE I/D with progressive renal failure (PRF) in autosomal dominant polycystic kidney disease (ADPKD) have been inconsistent, prompting a meta-analysis to obtain more precise estimates. Methods Multi-database search yielded 18 articles for inclusion in the meta-analysis. Risks (odds ratios [ORs] and 95% confidence intervals) were estimated by comparing the ACE genotypes (heterozygote ID, homozygotes DD and II). Heterogeneous (random-effects) pooled associations were subjected to outlier treatment which yielded fixed-effects outcomes and split the findings into pre- (PRO) and post- (PSO) outlier status. Subgroup analysis was based on ethnicity (Asian/Caucasian) and minor allele frequency (maf). The [&ge;]0.50 maf subgroup indicates higher frequency of the variant II genotype over that of the common DD genotype, otherwise, the subgroup is considered <0.50 maf. Stability of the associative effects was assess...Continue Reading
