Neurofibromatosis type I (NF1) is a monogenetic disorder caused by mutations in the NF1 gene encoding for the Ras-GAP protein neurofibromin. Apart from benign tumour development NF1 is frequently associated with skeletal manifestations such as osteopenia or debilitating focal skeletal dysplasia. To assess a function of Nf1 in osteocytes we here apply a combinatorial approach of biophysical, histological and molecular techniques allowing differential analysis ...
