Neurofibromatosis genetic testing: cohort study

Abstract

The study was conducted of DNA from peripheral blood of 1000 patients with clinical signs of neurofibromatosis type 1 or neurofibromatosis type 2. The genetic testing included massive parallel sequencing, multiplex ligation-dependent probe amplification, Sanger sequencing. The pathogenic mutation was identified in 70.2% of the cases, affecting NF1 and NF2 genes in 672 and 30 cases, respectively.
