LDLR Gene
Low Density Lipoprotein Receptor (LDLR) is a gene involved in LDL cholesterol clearance that has been studied in relation to immune function, metabolism, and chronic illness. Variants in LDLR may influence how the body responds to infection, inflammation, and long-term recovery.

What is the LDLR gene?
LDLR encodes low density lipoprotein receptor, a protein involved in LDL cholesterol clearance. It belongs to the Metabolic category and is part of the Metabolic Regulation biological cluster. LDLR encodes the LDL receptor on hepatocytes and other cells that clears LDL cholesterol from the circulation.
Biological role and pathway
LDLR is involved in the LDL cholesterol clearance pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Metabolic Regulation cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.
LDLR and Long COVID / ME-CFS research
LDLR variants affect LDL levels; hypercholesterolemia is a known COVID-19 severity risk factor, and LDLR variants may influence cardiovascular and metabolic aspects of Long COVID.

Known genetic variants
The following variants (SNPs) in the LDLR gene have been studied in relation to metabolic and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
Conditions studied in relation to LDLR
Research into LDLR variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that LDLR causes or treats any condition.
Genetic insights from DNA data
Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include LDLR and related genes in the metabolic regulation pathway.
The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.
