Abstract Background XK disease is a multisystem neurodegenerative disorder caused by mutations in the XK gene that codes for the lipid scramblase XK. Objective The aim was to describe the lipidomic spectrum in postmortem brain tissue from XK patients. Methods We measured the levels of 593 lipid species in the caudate nucleus (CN), putamen, and dorsolateral prefrontal cortex (DLPFC) from postmortem tissues of 5 XK patients and 6 controls. Results In XK patients, we observed increased levels of triacylglycerol, monoacylglycerol, phosphatidylserine, and ceramide in the CN. Acylated phosphatidylglycerol levels were reduced in both the CN and putamen. Acyl carnitine, dihydrosphingomyelin, and monosialodihexosylganglioside were reduced, whereas N ‐acyl phosphatidylethanolamine was increased in the DLPFC. N ‐Acyl serine was reduced in all three regions. Conclusions Our findings provide initial evidence of abnormal sphingolipid and phospholipid concentrations in the brains of XK patients and may provide insights into mechanisms of neurodegeneration in this disease. © 2026 International Parkinson and Movement Disorder Society.

Abstract Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with a life-time risk of 1 in 350 people and an unmet need for disease-modifying therapies. We conducted a cross-ancestry GWAS in ALS including 29,612 ALS patients and 122,656 controls which identified 15 risk loci in ALS. When combined with 8,953 whole-genome sequenced individuals (6,538 ALS patients, 2,415 controls) and the largest cortex-derived eQTL dataset (MetaBrain), analyses revealed locus-specific genetic architectures in which we prioritized genes either through rare variants, repeat expansions or regulatory effects. ALS associated risk loci were shared with multiple traits within the neurodegenerative spectrum, but with distinct enrichment patterns across brain regions and cell-types. Of the environmental and life-style risk factors obtained from literature, Mendelian randomization analyses indicated a causal role for high cholesterol levels. All ALS associated signals combined reveal a role for perturbations in vesicle mediated transport and autophagy, and provide evidence for cell-autonomous disease initiation in glutamatergic neurons.
