Mutations of the ELANE gene cause severe congenital neutropenia with periodontal disease: a case report / 华西口腔医学杂志

Severe congenital neutropenia is a rare disorder characterized by a consistently low absolute neutrophil count and periodontal disease. This report describes the case of an ELANE mutationin a patient with gingival bleeding and tooth mobility. Oral examination showed active periodontal infection of the primary dentition accompanied by alveolar bone loss in the posterior region. The patient was diagnosed with severe congenital neutropenia 1 year after multidisciplinary consultation. Treatment of the systemic disease and effective oral health education over a 3-year follow-up period relieved the periodontal infection and created favorable conditions for future repair.

New progress in genetic mechanisms of congenital neutropenia / 中华实用儿科临床杂志

Congenital neutropenia (CN) is a heterogeneous group of disorders in the inherited bone marrow failure syndromes (IBMFS),characterized by a severe decrease in the number of blood neutrophils,and a maturation arrest of bone marrow progenitor cells mainly at the promyelocyte/myeloid stage,and most of congenital neutropenia patients are susceptibility to bacterial infections in clinically.In recent years,the mutations in ELANE,GFI1,HAX1,G6PC3,WAS,CSF3R and so on are associated with the occurrence and development of CN,and with the further research,more new virulence gene will be found gradually.
