A Genome-Wide Association Study of Takotsubo Syndrome.

Studies have suggested a genetic susceptibility to Takotsubo syndrome. In this case-control genome-wide association study, we examined genetic risk variants associated with the condition. We identified 2 single-nucleotide polymorphisms, rs2073526 and rs1614887, highly expressed in the heart, with suggested association. Both were associated with several corresponding genes with an expression quantitative trait locus in the heart, with potential mechanistic pathways in metabolism and inflammation.
