The FABP4 level in HD males were significantly lower than that in HD females (Figure 1A; males vs. females: 315.8±30.0 vs. 404.2±30.5 ng/ml), and these levels were about 20-times higher than those in both male and female controls with normal renal function (Figure 1B; males vs. females: 16.0±1.7 vs. 20.5±1.6 ng/ml). Here, FABP4 is linked to Huntington disease.
