This guide explains the rarer form of non-HFE genetic haemochromatosis, also known as type 3 or TFR2-related GH.

Although this form of the condition is considered rare, increasing levels of genetic testing for this variant are revealing more people at risk of the condition, particularly in combination with a type 1 (HFE) mutation to either C282Y, H63D or S65C genes.
