摘　　要：BACKGROUND Neurofibromatosis is an autosomal dominant genetic disorder with various manifestations.Systemic multiple neurofibromatosis is rare in infancy.The disease is difficult to identify in the early stage,and it is prone to misdiagnosis and missed diagnosis.In the presence of lower limb swelling with subcutaneous nodules of unknown cause,café-au-lait spots,and axillary freckles,this disease must be considered.This report presents the clinical manifestations,early detection,diagnosis and treatment,and prognosis of infantile neurofibromatosis type I(NF1).CASE SUMMARY The clinical manifestations,imaging examinations,and gene results of a 3-mo-old male infant with NF1 were analyzed retrospectively.He had“swelling of both legs”at the onset and developed café-au-lait spots,axillary freckles,and multiple neurofibromas later.He had a family history of similar conditions.Gene detection showed a heterozygous mutation of c.4537C>T in the NF1 gene,leading to a nonsense mutation of amino acids(p.R1513x),which originated from the mother of the infant.He was diagnosed with NF1.CONCLUSION Gene diagnosis plays an important role in the early diagnosis of NF1.
