Neurofibromatosis Type 1 in Ecuador: genotype-phenotype correlations from a case series

This case series expands the mutational and phenotypic spectrum of NF1 in a pediatric Ecuadorian cohort. Findings underscore the diagnostic value of early pigmentary signs and highlight less commonly reported manifestations such as radial bone dysplasia and prepubertal gynecomastia. Integrating molecular diagnostics with early clinical evaluation may enable earlier and more precise diagnosis, guiding personalized management strategies. Further studies should investigate genotype-phenotype correlations and the influence of ancestry on NF1 expression.
