TFRC and non-alcoholic fatty liver: The effects of pQTLs of the transferrin receptor protein 1 (TFRC) were proportional to their effect on PDFF (Pivw-olink = 5.6 × 10−10, Pivw-somascan = 2.0 × 10−4; Supplementary Fig. 13 and Supplementary Table 11), suggesting that TFRC may have a causal role in NAFL.
