However, in the group of PKU patients, those who had a good metabolic control displayed higher HDL-C concentrations and LDL/ApoB ratio than those with poor metabolic control (50.4 ± 12.02 vs. 47.4 ± 11.26 mg/dL and 1.22 ± 0.19 vs. 1.20 ± 0.23, respectively); although these differences did not reach statistical significance. The gene discussed is APOB; the disease is phenylketonuria.
