What is the GCDH gene?
Mitochondrial glutaryl-CoA dehydrogenase supporting lysine, hydroxylysine, and tryptophan catabolism with organic-acid and acylcarnitine readouts.
How GCDH affects metabolism
When GCDH-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 GCDH is altered
Altered GCDH 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 GCDH
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
GCDH currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

Glutaryl-CoA dehydrogenase activity tendency
rs121434367 T / GCDH c.1262C>T / p.Ala421Val is associated with lower glutaryl-CoA dehydrogenase activity and higher glutaric-acid, 3-hydroxyglutaric-acid, and glutarylcarnitine burden in recessive or compound-heterozygous glutaric acidemia type 1 contexts.
GCDH rs121434367 T is staged as a pathogenic glutaric acidemia type 1 allele affecting mitochondrial organic-acid 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 GCDH 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
GCDH 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 GCDH 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.
