To study pathogenetic mechanisms of the development of spinal deformity in neurofibromatosis.Structural components of the spine were presented as specimens obtained after surgical correction of spinal deformity performed in 10 children with III—IV grade scoliosis associated with neurofibromatosis.Etiologic factor of the development of spinal deformity in neurofibromatosis is a mutation of the NF-1 gene in cells of ganglious lamella. Migration of cells carrying mutant gene into one of the
