Hemoglobin has plenty of variants and fast moving hemoglobins (FMH’s) are the rare hemoglobin variants. They are having tendency to migrate anodally to hemoglobin A on alkaline gel electrophoresis. Because of the mutation in the globin genes, these hemoglobin variants have the fast moving nature. The basic pathophysiology behind it is the substitution of a negatively charged amino acid residue in either α, β or γ globin chains. Hb J Meerut is an infrequently found α-globin variant. It has previously been reported in various populations around the world. Here, we are reporting a case of Hb J meerut who came to laboratory for thalassemia screening.
