NTRK1 and hydrops fetalis: After 4 weeks of dietary intervention, IENFD (Std: 32.2 ± 1.3, HF: 39.4 ± 1.2 fibers/mm, p = 0.004) and TrkA nerve fiber density (Std: 22.4 ± 1.3, HF: 30.4 ± 1.8 fibers/mm, p = 0.001 were greater in HF compared to Std (Figures 3A,B), but there was no difference between diet groups in IENFD (Std: 33.6 ± 1.5, HF: 34.1 ± 1.6 fibers/mm, p = 0.839) or TrkA nerve fiber density (Std: 26.2 ± 1.4, HF: 26.4 ± 1.3 fibers/mm, p = 0.939) after 8 weeks.
