As demonstrated in several recent publications [18,19,20], we also observed that the association between plasma fetuin-A levels and the AT-IR index was stronger with increasing fasting plasma NEFA concentrations [standardized beta (Bstd) = 0.11 and p = 0.034 increase in the AT-IR index per standard deviation increase in plasma fetuin-A levels interacted with fasting NEFA levels (mcg/mL × mmol/L)]. The gene discussed is AHSG; the disease is ataxia telangiectasia.
