What is the LCAT gene?
Lecithin-cholesterol acyltransferase esterifying cholesterol on HDL and supporting HDL particle maturation.
How LCAT affects metabolism
When LCAT-related function is shifted, the practical effect is interpreted through lipoprotein transport, triglyceride-rich particles, LDL clearance, or liver lipid handling. This does not mean the pathway is active or impaired right now; it means the gene can help prioritize what to check next.
What happens when LCAT is altered
Altered LCAT signal should be treated as a DNA-based tendency, not a diagnosis. 1 claim currently passes the report-use gate. The useful question is whether symptoms, labs, and lifestyle context line up with the pathway signal.
Curated SNP evidence for LCAT
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
LCAT currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

LCAT HDL cholesterol esterification activity tendency
rs121908050 A (forward-genomic; LCAT c.440C>T / p.Thr147Ile transcript context) is associated with lower alpha-LCAT HDL cholesterol esterification activity tendency and low HDL cholesterol in fish-eye disease contexts.
LCAT rs121908050 A is staged as the forward-genomic pathogenic fish-eye disease allele affecting HDL cholesterol esterification.

Common symptoms people report
- unexpected cholesterol or triglyceride results
- family context around lipid markers
- unclear ApoB, LDL-C, HDL-C, or triglyceride patterns
Biomarkers to validate
ApoB
Shows the number of atherogenic particles more directly than total cholesterol.
LDL-C, HDL-C, and triglycerides
Gives the basic lipid pattern that DNA can help contextualize.
Lp(a) or liver enzymes when relevant
Adds context for inherited lipid risk or liver lipid handling.
Where DNA analysis helps
DNA helps decide whether LCAT deserves attention inside the broader Lipids pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
LCAT may add context to lipoprotein transport, triglyceride-rich particles, LDL clearance, or liver lipid handling, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: ApoB.
What to do next
- Review the Lipids pathway result before interpreting LCAT on its own.
- Use relevant biomarkers to confirm whether this DNA tendency is visible in current biology.
- Treat supplement or nutrition decisions as follow-up steps only after the pattern fits symptoms or labs.
