APOB Gene

Apolipoprotein B (APOB) is a gene involved in lipid transport that has been studied in relation to immune function, metabolism, and chronic illness. Variants in APOB may influence how the body responds to infection, inflammation, and long-term recovery.

What is the APOB gene?

APOB encodes apolipoprotein b, a protein involved in lipid transport. It belongs to the Metabolism category and is part of the Mitochondrial & Metabolic biological cluster. ApoB is the structural protein of LDL, VLDL, and IDL particles and the sole apoprotein of LDL. APOB variants affect LDL levels and cardiovascular disease risk. Familial defective ApoB causes elevated LDL.

Biological role and pathway

APOB is involved in the lipid transport pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Mitochondrial & Metabolic 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.

APOB and Long COVID / ME-CFS research

Lipid dysregulation is documented in COVID-19 and Long COVID, with altered HDL/LDL profiles. Elevated LDL contributes to COVID-19-related cardiovascular complications and accelerated atherosclerosis. APOB variants affecting LDL particle levels may influence Long COVID cardiovascular risk.

Known genetic variants

The following variants (SNPs) in the APOB gene have been studied in relation to metabolism and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

Conditions studied in relation to APOB

Research into APOB variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that APOB 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 APOB and related genes in the mitochondrial & metabolic 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.

Frequently asked questions

What is the APOB gene and what does it do?

APOB (Apolipoprotein B) is involved in lipid transport. ApoB is the structural protein of LDL, VLDL, and IDL particles and the sole apoprotein of LDL. APOB variants affect LDL levels and cardiovascular disease risk. Familial defective ApoB causes elevated LDL.

How may APOB gene variants relate to Long COVID or ME/CFS?

Lipid dysregulation is documented in COVID-19 and Long COVID, with altered HDL/LDL profiles. Elevated LDL contributes to COVID-19-related cardiovascular complications and accelerated atherosclerosis. APOB variants affecting LDL particle levels may influence Long COVID cardiovascular risk.
