Neurofibromatosis type 1 is a common autosomal-dominant neurocutaneous disorder with broad molecular and clinical heterogeneity. Pediatric patients frequently present early with pigmentary findings, neurodevelopmental issues, and risk of tumor development, including plexiform neurofibromas. In this paper, we aimed to synthesize recent advances in the molecular genetics of neurofibromatosis type 1 and genotype-phenotype correlations, and to illustrate clinical variability through three anonymized pediatric cases.
