What is the DLD gene?
Mitochondrial dihydrolipoamide dehydrogenase E3 subunit shared by pyruvate, alpha-ketoglutarate, and branched-chain alpha-ketoacid dehydrogenase complexes.
How DLD affects metabolism
When DLD-related function is shifted, the practical effect is interpreted through fatty-acid oxidation, mitochondrial transport, organic-acid handling, or high-demand energy metabolism. 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 DLD is altered
Altered DLD 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 DLD
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
DLD currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

DLD/E3 mitochondrial redox dysfunction tendency
rs121964990 T / DLD c.685G>T / p.Gly229Cys is associated with pathogenic DLD deficiency and mitochondrial E3 redox dysfunction, including increased ROS-generating activity context, in recessive or compound-heterozygous deficiency contexts.
DLD rs121964990 T is staged as a pathogenic DLD deficiency allele affecting shared E3/lipoamide dehydrogenase redox handling.

Common symptoms people report
- low energy under fasting, illness, or exercise
- slow recovery after exertion
- fatigue that feels out of proportion to workload
Biomarkers to validate
CBC, ferritin, and thyroid context
Rules out common non-DNA explanations for low energy.
Glucose and HbA1c
Checks whether fuel handling is adding pressure.
Organic acids or acylcarnitines when available
Adds more specific mitochondrial and fatty-acid oxidation context.
Where DNA analysis helps
DNA helps decide whether DLD deserves attention inside the broader Mitochondrial energy pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
DLD may add context to fatty-acid oxidation, mitochondrial transport, organic-acid handling, or high-demand energy metabolism, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: CBC, ferritin, and thyroid context.
What to do next
- Review the Mitochondrial energy pathway result before interpreting DLD 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.
