title: [Biochemical and clinical studies of 2 new Italian cases of Hb G-Ferrara heterozygosis].
abstract: The Authors report the data concerning a family coming from Ficarolo (Rovigo). The father and one son were found hematologically healthy, but resulted carriers of Hb G-Ferrara. This is an unstable rare pigment with a replacement in the beta 57 (E-1) helicoidal position. The type and site of the mutation explain the "in vitro" molecular instability; on the other hand, this latter doesn't seem to cause any hematological disorder, even if an increased met-Hb production was found when affected blood was incubated at 37 degrees C for two hours in sterile conditions.
