[mandyjane]

Does anybody know of an endo near or in Bristol on NHS who is prescribing T3. PM me please if you have any information re this.

For clarity, the gene that affects T4 to T3 conversion is called DIO2 - that is, three letters and a number. Not D102 - a letter and three numbers. Not DI02 - two letters and two numbers.

The name comes from the enzyme that this gene affects which is a deiodinase. It removes an iodine atom from a thyroid hormone molecule - it deiodinates it.

On this forum we probably understand, but if you wish to look it up anywhere, it might help to get it right. If you are discussing with a doctor, and get it wrong, you are providing an excuse for them to dismiss what you say.

(More strictly, two single-nucleotide polymorphisms (SNPs) on the DIO2 gene, rs225014 and rs225015.)

The Wiki article provides a basic introduction as to what a single-nucleotide polymorphism (SNP) is and why it can be important:
