An enormous Italian pedigree of Marfan syndrome with a novel mutation in the FBN1 gene.

We characterize a large Italian family presenting with Marfan syndrome (MFS), where the same NM_000138.4:c.6872-1G > T splice site mutation in the FBN1 gene was detected in 37 affected individuals with different pathological phenotypes.

Biophysical characterisation of the recombinant human frataxin precursor.

Friedreich's ataxia is a disease caused by a decrease in the levels of expression or loss of functionality of the mitochondrial protein frataxin (FXN). The development of an active and stable recombinant variant of FXN is important for protein replacement therapy. Although valuable data about the mature form FXN81-210 has been collected, not enough information is available about the conformation of the frataxin precursor (FXN1-210).
