An autosomal dominant inherited disorder (with a high frequency of spontaneous mutations)
that features developmental changes in the nervous system, muscles, bones, and skin,
most notably in tissue derived from the embryonic NEURAL CREST. Multiple hyperpigmented
skin lesions and subcutaneous tumors are the hallmark of this disease. Peripheral
and central nervous system neoplasms occur frequently, especially OPTIC NERVE GLIOMA
and NEUROFIBROSARCOMA. NF1 is caused by mutations which inactivate the NF1 gene (GENES,
NEUROFIBROMATOSIS 1) on chromosome 17q. The incidence of learning disabilities is
also elevated in this condition. (From Adams et al., Principles of Neurology, 6th
ed, pp1014-18) There is overlap of clinical features with NOONAN SYNDROME in a syndrome
called neurofibromatosis-Noonan syndrome. Both the PTPN11 and NF1 gene products are
involved in the SIGNAL TRANSDUCTION pathway of Ras (RAS PROTEINS)
Note publique d''information :
A syndrome characterized by the presence of PULMONARY STENOSIS; CAFE-AU-LAIT SPOTS;
MENTAL RETARDATION; and short stature caused by mutations in the NF1 gene (GENES,
NEUROFIBROMATOSIS 1)
Note générale sur le champ d'application :
do not confuse with NEUROFIBROMATOSIS 2; coord IM with precoord organ/neopl term (IM)
if relevant
