Regarding LH levels, no differences were found when comparing patients with or without retinopathy or AN, but patients with nephropathy presented significantly higher LH levels (9 ± 7 IU/L vs. 6 ± 3 IU/L, t = 3.052, p < 0.005) as did those with peripheral neuropathy (9 ± 7 IU/L vs. 6 ± 5 IU/L, t = 2.852, p < 0.005). The gene discussed is PLOD1; the disease is Nephropathy.
