What is the ABCG8 gene?
ABCG8 works with ABCG5 to transport cholesterol and plant sterols. Common variants are interpreted as biomarker context, separate from rare sterol-transport disorders.
How ABCG8 affects metabolism
An ABCG8 signal may make cholesterol absorption and LDL-C follow-up more relevant, but it does not diagnose sitosterolemia or a cardiovascular condition.
What happens when ABCG8 is altered
Common ABCG8 evidence should stay modest and be checked against ApoB, LDL-C, and clinical context.
Curated SNP evidence for ABCG8
These SNPs come from the approved study-level evidence model. Each claim is scored from curated study rows, then gated before it can influence pathway scoring.
Evidence-backed report connection
ABCG8 currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

ABCG8 sterol transport and LDL cholesterol tendency
rs4299376 GT carries one ABCG8 rs4299376 G allele and is associated with higher LDL cholesterol and cholesterol-absorption tendency.
ABCG8 rs4299376 GT is staged as a heterozygous sterol-transport/LDL-C tendency signal.

Common symptoms people report
- unexpected LDL-C patterns
- family context around cholesterol
- questions about cholesterol absorption versus synthesis
Biomarkers to validate
LDL-C
Primary cholesterol marker linked to the common-variant evidence.
ApoB
Shows apoB-containing particle number.
Sterol markers when available
Can help separate absorption and synthesis context.
Where DNA analysis helps
DNA helps decide whether sterol transport deserves follow-up inside the Lipids pathway.
Example interpretation
ABCG8 may add useful context when its SNP evidence lines up with the broader pathway signal.
Suggested validation: LDL-C, ApoB, and sterol markers if relevant.
What to do next
- Check standard lipid markers first.
- Use sterol markers only when clinically appropriate.
- Keep rare disease interpretation separate from common SNP context.
