ABCC9 encodes the SUR2 subunit of KATP channels and dominant genetic variants in ABCC9 have been associated with cardiac phenotypes. Here, the authors report recessive ABCC9 mutations in individuals with mild intellectual disability, myopathy and cardiac systolic dysfunction which is associated with loss of KATP channel function.
