GWAS have identified risk loci for osteoarthritis (OA), but the causal variants still have to be determined. Here, the authors apply a massively-parallel reporter assay to screen 1,605 candidate SNPs in 35 OA loci, which prioritizes six SNPs in four loci, one of which, rs4730222, is characterized in more detail.
