Like STAG1, KLC1 resides within a schizophrenia GWAS locus containing multiple genes (Fig. 2), but in that instance, the 95% credible set of causal variants was dispersed across 23 genes4; by implicating missense variants in KLC1 in schizophrenia at FDR < 5%, our study supports the prioritisation of this gene within its GWAS locus. This evidence concerns the gene STAG1 and schizophrenia.
