Severe poikilocytosis associated with a de novo alpha 28 Arg-->Cys mutation in spectrin.

Abstract excerpt

Severe poikilocytosis was observed in an Italian child. The mutation responsible was a de novo alpha 28 Arg-->Cys substitution (CGT-->TGT) in spectrin, a mutation known to cause hereditary elliptocytosis or hereditary pyropoikilocytosis. In this particular case the severity of the manifestations were accounted for by the occurrence, in trans to the alpha 28 mutation, of the alpha V/41 polymorphism. The latter has...
