Rev Assoc Med Bras. Niimura M. The Parthenon Publishing Group Inc. Support Center Support Center. Previous genetic mapping had narrowed the search for the gene to a particular spot on chromosome The new research has identified the specific location of the gene and much of its nucleic acid sequence. In some patients, the gene is severed by a chromosomal translocation, thereby eliminating the expression of the protein encoded by the gene.

In other patients, a point mutation in the gene changes one nucleic acid, which changes one amino acid in the encoded protein and presumably alters the normal function of the protein. The gene also has a high rate of spontaneous mutation.

An attractive hypothesis is that most patients with NF1 are born with one defective allele for the gene in every cell; when a postnatal somatic mutation arises in the second allele in a cell derived from neural crest, a neurofibroma begins growing.

This hypothesis can now be tested, prenatal diagnostic tests can be developed, and the molecular basis for NF1 can be pursued. Cawthon RM et al. A major segment of the neurofibromatosis type 1 gene: cDNA sequence, genomic structure, and point mutations. Cell 62 Wallace MR et al.
