The highly variable clinical features of NF1 are because of there are many genetic modifiers that lie outside the NF1 gene, which influence NF 1 gene and account for a large fraction of the symptomatic variability seen in NF1. Mutation detection in the NF1 gene is complex due to its large size, the existence of several pseudo genes and the lack of clustering of the mutations. There are no clear mutation hotspots and the spectrum of mutations is very diverse, ranging from micro deletions affecting the entire NF1 gene to minor lesions that include a high proportion of splicing mutations.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Objective<\/jats:bold>\n                      : Identification of the genetic mutation in mother son duo with neurofibromatosis.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Method<\/jats:bold>\n                      : Whole exome analysis was performed to identify the genetic defect.
