Genetic risk factors for Mesoamerican nephropathy.

ABSTRACT: Mesoamerican nephropathy (MeN) is a progressive kidney disease found on the Pacific coast of Central America primarily in young male agricultural workers without typical kidney disease risk factors. While it is generally accepted that environmental exposures contribute to MeN, we hypothesized that there was also an important genetic component. We performed a genome-wide association study comparing individuals with MeN versus individuals with normal kidney function. We found that Native American ancestry was strongly associated with increased risk of MeN. We also identified candidate variants in the OPCML gene, which encodes a protein that binds opioid receptors, that were associated with ~sixfold reduced odds of MeN (allele frequency 0.029 in controls and 0.005 in cases, OR = 0.16;
