HFE gene mutation and transferrin saturation in very low birthweight infants
1Department of Neonatology Charité Virchow Hospital Humboldt University D-13353 Berlin Germany.
Insights
This study found no link between high transferrin saturation and the C282Y HFE gene mutation in very low birthweight (VLBW) infants. These findings suggest iron overload is unlikely related to this specific gene mutation in this vulnerable population.
Area of Science:
- Neonatal Medicine
- Genetics
- Pediatric Hematology
Background:
- Very low birthweight (VLBW) infants often receive iron supplementation.
- High transferrin saturation can indicate iron overload.
- The C282Y mutation in the HFE gene is associated with hereditary hemochromatosis.
Purpose of the Study:
- To investigate the potential association between elevated transferrin saturation and the C282Y HFE gene mutation in VLBW infants.
- To assess the risk of iron overload related to HFE gene mutations in this specific infant population.
Main Methods:
- Studied 143 VLBW infants receiving recombinant erythropoietin and enteral iron.
- Analyzed genomic DNA from filter paper cards for the C282Y mutation using restriction fragment length polymorphism.
- Monitored transferrin saturation levels.
Main Results:
- Six infants were heterozygous for the C282Y mutation; none were homozygous.
- Ten infants exhibited transferrin saturation above 80% at least once.
- No infant presented with both high transferrin saturation and the C282Y mutation.
Conclusions:
- The study found no evidence of an association between high transferrin saturation and the C282Y HFE gene mutation in VLBW infants.
- These findings suggest that iron overload in VLBW infants during early life is unlikely to be linked to the C282Y HFE mutation.
Aim:
To determine if there is an association between high transferrin saturation and the C282Y HFE gene mutation in very low birthweight (VLBW) infants.
Methods:
One hundred and forty three VLBW infants receiving recombinant erythropoietin and 3 to 9 mg/kg/day of enteral iron were studied. Genomic DNA was extracted from filter paper cards. The C282Y mutation was determined by restriction fragment length polymorphism analysis.
Results:
Six infants were heterozygous for the mutation; none was homozygous. Ten infants had a transferrin saturation above 80% at least once. No infant was positive for both transferrin saturation above 80% and the mutation.
Conclusions:
The data strongly suggest that there is no association between high transferrin saturation and the HFE gene mutation in VLBW infants during the first weeks of life.
