Proportional Testing for Colocalisation Analysis R package colocPropTest version 0.9.3 Colocalisation analysis tests whether two traits share a causal genetic variant in a specified genomic region. Proportional testing for colocalisation has been previously proposed [Wallace (2013) <doi:10.1002/gepi.21765>], but is reimplemented here to overcome barriers to its adoption. Its use is complementary to the fine- mapping based colocalisation method in the 'coloc' package, and may be used in particular to identify false "H3" conclusions in 'coloc'.
