    R&D Systems plasma fgf21 levels
    Age and ex-matched SLC25A13 mutation carriers from the TWB were assayed for <t>FGF21</t> circulation and urinary sodium. The data show that male (A) and female (B) mutation carriers have higher levels of FGF21 than control participants and that male and female mutation carriers have higher levels of urinary sodium (C) than control participants. Further, female CD patients have much higher levels of circulating FGF21 than control female age-matched participants (D).

    (A) TGs were compared between the N = 7 control participants and the N =45 SLC25A13 mutation carriers for whom TG values were available in the TWB. These data show a nonsignificant TG increase in mutation carriers. (B) A plot of TGs as a function of FGF21 in mutation carriers shows a strong positive correlation (Pearson’s correlation R = 0.58) that is counter to the depression of TGs by genetically proxied FGF21 in the general population and consistent with elevation of FGF21 and lipogenic transcription by a potentiated ChREBP system in SLC25A13 carriers.
