PPS for biomarkers of lipid metabolism explained 1.2%–13.1% of their variance at diagnosis. None of the PPS was significantly associated with survival (all p > 0.50).Discussion Lipids may contain valuable information about disease severity and prognosis, but their main value may be driven as a consequence of disease progression. Our results underscore that gaining further insight into lipid metabolism and longitudinal data on serum concentrations of the lipid profile could improve the monitoring of patients and potentially further disentangle ALS pathogenesis.ALS=amyotrophic lateral sclerosis; ALSFRS=ALS functional rating scale; BMI=body mass index; EEC=El Escorial criteria; ENCALS=European Network to Cure ALS; FTD=frontotemporal dementia; HDL=high-density lipoprotein; HDL-C=HDL cholesterol; HR=hazard ratio; LDL-C=low-density lipoprotein cholesterol; PPS=polygenic profile score; TC=total cholesterol; TG=triglycerides
