It causes characteristic clinical manifestations, including facial dysmorphism and congenital cardiac defects. Occasionally, lymphoedema and recurrent cellulitis occur in patients with NS, potentially escalating to lethal conditions. Despite the frequent association of cellulitis with lymphoedema in NS, features susceptible to these complications have not been fully characterized. We encountered two patients with NS carrying RIT1 pathogenic variants, who were treated for recurrent lower leg cellulitis since their teenage years, which occasionally progressed to sepsis. Here we retrospectively examined these patients with NS and recurrent cellulitis on the background of lymphoedema and reviewed published cases of NS with lymphoedema and cellulitis up to March 2024 to elucidate the clinical and genetic features of this subgroup. Our literature review identified 16 additional patients with NS with similar complications. Among the 18 patients (15 men), genetic analyses revealed pathogenic variants in PTPN11 and RIT1 in 4 patients each, with the latter occurring more frequently than commonly observed. The patients developed lymphoedema by 15 years of age, predisposing them to cellulitis by 23 years of age. Notably, four of the five patients with sepsis had congenital heart defects, with a higher prevalence than that generally reported in NS. This study highlights the characteristics of genetic variants, congenital cardiac anomalies and heightened risk of recurrent cellulitis in patients with NS, emphasizing the need for early intervention with prophylactic antibiotics and surgical treatment to mitigate these risks.</p>","PeriodicalId":36861,"journal":{"name":"Human Genome Variation","volume":"12 1","pages":"12"},"PeriodicalIF":1.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12137658/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144227020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
