What is the PGM1 gene?
Phosphoglucomutase interconverting glucose-1-phosphate and glucose-6-phosphate for glycogen metabolism and glycosylation support.
How PGM1 affects metabolism
When PGM1-related function is shifted, the practical effect is interpreted through meal response, fasting glucose control, insulin signaling, or glucose transport. 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 PGM1 is altered
Altered PGM1 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 PGM1
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
PGM1 currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

Phosphoglucomutase activity tendency
rs397515423 T / PGM1 c.1507C>T / p.Arg503Ter is associated with lower phosphoglucomutase activity and impaired glucose-1-phosphate/glucose-6-phosphate interconversion in recessive or compound-heterozygous PGM1 deficiency contexts.
PGM1 rs397515423 T is staged as a truncating PGM1 deficiency allele affecting glucose-phosphate interconversion, glycogen handling, and glycosylation biomarkers.

Common symptoms people report
- sleepiness or fog after carbohydrate-heavy meals
- energy swings between meals
- family or lab concern around glucose markers
Biomarkers to validate
Fasting glucose and HbA1c
Checks baseline blood-sugar control.
Fasting insulin
Helps identify insulin-demand context that glucose alone can miss.
Triglycerides and HDL-C
Adds metabolic context around meal response and insulin resistance.
Where DNA analysis helps
DNA helps decide whether PGM1 deserves attention inside the broader Glucose pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
PGM1 may add context to meal response, fasting glucose control, insulin signaling, or glucose transport, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: Fasting glucose and HbA1c.
What to do next
- Review the Glucose pathway result before interpreting PGM1 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.
