The Claim
Heterozygous DIO1 deficiency in mice (Dio1-Het) results in elevated serum reverse triiodothyronine and increased rT3/T3 ratios, mirroring the biochemical phenotype observed in humans.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Mice with one defective copy of the DIO1 gene show higher levels of reverse T3 and a higher reverse T3 to T3 ratio in their blood, just like humans with the same genetic condition.
See the scientific wording
Heterozygous DIO1 deficiency in mice (Dio1-Het) replicates the human biochemical phenotype of elevated serum reverse triiodothyronine and increased rT3/T3 ratios, supporting the biological plausibility of haploinsufficiency as the disease mechanism.
When only one copy of the DIO1 gene works, the enzyme it produces cannot process thyroid hormones efficiently. This causes the body to build up reverse T3 and produce less active T3, because the enzyme is not working at full strength.
What the research says
1 studyStudy: Human Type 1 Iodothyronine Deiodinase (DIO1) Mutations Cause Abnormal Thyroid Hormone Metabolism
Scientists found that people and mice with only one working copy of the DIO1 gene both have the same weird thyroid hormone pattern, proving that losing half the gene’s function is enough to mess up hormone balance.
