In fact, the observed lower cg00574958 methylation in the FH mutation-negative patients thus might be explained by the higher triglyceride levels in this group compared to the group of FH patients where a causative variant was identified (Table 1), since triglyceride levels were also found to negatively correlate with cg00574958 methylation in our study. The gene discussed is FH; the disease is familial hyperaldosteronism.
