Therefore, the regional variations of blood n-3 PUFA status in dialysis patients could be a plausible explanation for the differences in CRP levels reported in the Dialysis Outcomes and Practice Patterns Study, where Japanese HD patients exhibited lower CRP levels (1.0 mg/L) than their counterparts from other countries (6.0 mg/L) [79]. The gene discussed is CRP; the disease is Huntington disease.
