Characterisation of germline mutations in the neurofibromatosis type 1 (NF1) gene.

abstract：:We describe the clinical and cytogenetic findings of two patients with deletions of the long arm of chromosome 2. One has an interstitial deletion identical to that found in a previously reported patient, although they are phenotypically dissimilar.
