Linear regression was used to test the association of suggestive signals
for all-cause heart failure and nonischemic cardiomyopathy variants with
measured cardiac MRI traits in up to 4,158 individuals free of clinical heart
failure in the UK Biobank. Testing was performed using allelic dosages,
adjusting for age at baseline, sex, genotyping chip, and the first 10 principal
components of ancestry. Results are displayed for (a) rs2234962 near
BAG3 and (b) rs10927875 near ZBTB17
against three selected cardiac MRI traits as no other variants had associations
reaching statistical significance. Points represent the effect in SD units of
each respective cardiac MRI trait and error bars denote 95% confidence
intervals. Significant associations passing Bonferroni significance
(P < 0.05 / 42 = 1.19×10−3)
are denoted with a star (*). Abbreviations: NICM=nonischemic cardiomyopathy;
β=effect per NICM risk allele in SD units of the cardiac MRI trait;
SD=standard deviation.
