FAQ icd 10 code for neurofibroma
What are neuromuscular neurofibromas?
Neurofibromas are benign Schwann cell tumors that are classified according to their appearance and location: focal or diffuse cutaneous, subcutaneous, nodular or diffuse plexiform, and spinal.
What is the pathophysiology of neurofibromatosis type I (NF1)?
In a patient with neurofibromatosis type I (NF1; 162200) who had onset of neurofibromatous neuropathy at the age of 42 years, Ferner et al. (2004) identified a 1-bp deletion (4071delC) in exon 23.2 of the NF1 gene, resulting in a premature stop codon. The deletion was predicted to generate a truncated neurofibromin of 1,383 amino acids.
What is neurofibromin 3 and 4?
Neurofibromins 3 and 4, which contain exon 48a and both exons 23a and 48a, respectively, are expressed in muscle tissue, mainly in cardiac and skeleton muscles. Neurofibromin 9a (also called 9br) is the result of the inclusion of exon 9a and shows limited neuronal expression.
What is r365x in neurofibromatosis?
Independently, Cawthon et al. (1990) and Estivill et al. (1991) identified a new mutation in exon 4 of the NF1 gene, a 1087C-T transition (numbering of Cawthon et al., 1990 ), resulting in an arg365-to-ter (R365X) substitution, in patients with neurofibromatosis type I (NF1; 162200 ).
