What is hemoglobin j? Does it have any relationship with alpha thalassemia?

In brief: Uncertain

Hemoglobin j is actually a group of at least 50 variants that share a common rapid mobility in electrophoresis and ief.
Mutations can occur in either the Alpha or beta chains. Most oftenpresent in the heterozygous state and clinically silent. Because of this, and the limited information about them in relation to other abnormal hemoglobins, a relationship with thalassemia syndromes is not known.

In brief: Mutated

This is a group of mutated hemoglobins that travel fast on electrophoresis.
Most are non-problems. Unlike in the thalassemias, in which the portion of the gene that determines whether the chains get transcribed and translated, here the mutation is in the chains themselves. Your physician can tell you more about which "j" you happen to have. Best wishes.
