NEFH and familial hyperaldosteronism: In addition, in FH a significant reduction in expression of proteins responsible for iron storage was observed: FT-H (ng/mg; NFH 28.1 ± 5.0 vs. FH 23.5 ± 3.8; p = 0.0189); FT-L (ng/mg; NFH 22.1 ± 7.4 vs. FH 15.0 ± 5.7; p < 0.0001); and FT-MT (ng/mg; 55.9 ± 12.4 vs. 39.1 ± 6.1; p < 0.0001), as compared to NFH.
