    Summary
    This gene product appears to function as a negative regulator of the ras signal transduction pathway. Mutations in this gene have been linked to neurofibromatosis type 1, juvenile myelomonocytic leukemia and Watson syndrome. The mRNA for this gene is subject to RNA editing (CGA>UGA->Arg1306Term) resulting in premature translation termination. Alternatively spliced transcript variants encoding different isoforms have also been described for this gene. [provided by RefSeq, Jul 2008]

    Summary from GeneReviews: Go to GeneReviews

    Disease Characteristics
    Neurofibromatosis 1 (NF1) is characterized by multiple caf au lait spots, axillary and inguinal freckling, multiple discrete cutaneous neurofibromas, and iris Lisch nodules. Learning disabilities are present in at least 50% of individuals with NF1. Less common but potentially more serious manifestations include plexiform neurofibromas, optic nerve and other central nervous system gliomas, malignant peripheral nerve sheath tumors, scoliosis, tibial dysplasia, and vasculopathy.
    Diagnosis Testing
    The diagnosis of NF1 is usually based on clinical findings. Heterozygous mutations of the NF1 gene are responsible for the vast majority of cases of neurofibromatosis. Molecular genetic testing of the NF1 gene is available clinically but is infrequently needed for diagnosis.
    Genetic Counseling
    NF1 is inherited in an autosomal dominant manner. Half of affected individuals have NF1 as the result of a de novo NF1 gene mutation. The offspring of an affected individual have a 50% risk of inheriting the altered NF1 gene, but the disease manifestations are extremely variable, even within a family. Prenatal testing for pregnancies at increased risk is possible if the disease-causing mutation in a family is known.

    NCBI Reference Sequences (RefSeq)

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
