After the 11-week HF feeding, the three genotypes were significantly different from each other (IFABP−/− vs. WT p = 0.041, R2 = 0.29; LFABP−/− vs. WT p = 0.028, R2 = 0.22; IFABP−/− vs. LFABP−/−p = 0.004, R2 = 0.58), and the dissimilarity between IFABP−/− and WT was similar to that between LFABP−/− and WT. Here, FABP1 is linked to hydrops fetalis.
