LRP10 (LDL Receptor-Related Protein 10) is a member of the low-density lipoprotein receptor family. LRP10 is a transmembrane receptor involved in endosomal-lysosomal trafficking and protein clearance. Rare coding variants in LRP10 are associated with an increased risk of Parkinson's disease and dementia with Lewy bodies.
