Variants inherited maternally lead to reduced Gsα activity in certain tissues, resulting in resistance to multiple hormones and manifesting clinically as pseudohypoparathyroidism (PHP). In contrast, paternal transmission is linked to pseudopseudohypoparathyroidism (PPHP), which is characterized by extensive ectopic cutaneous ossification but lacks endocrine resistance. Thus, the phenotypic spectrum arising from GNAS gene variants is profoundly influenced by the parent-of-origin effect. Objectives: To analyse the clinical characteristics and GNAS gene variants of six patients with ectopic cutaneous ossification. We retrospectively analysed six patients with GNAS-related ectopic cutaneous ossification, with evaluation of clinical features, laboratory results, histopathology, and genetic testing data. Six patients presented with cutaneous ossification and Albright hereditary osteodystrophy (AHO) phenotype associated with GNAS gene variants. The identified variants comprised a splicing mutation (c.718+1G>A), two nonsense mutations (c.91C>T and c.103C>T), and three frameshift mutations (c.518_521del, c.565_568del, and c.522_523del). Notably, the frameshift variant c.522_523del has not been previously reported in the literature. Five patients were diagnosed with PHP, one with PPHP. This study expands the mutational spectrum of GNAS by identifying a novel variant and highlights the phenotypic heterogeneity of GNAS-associated disorders. Early molecular diagnosis, integrated with clinical evaluation, is essential for timely intervention, mitigating disease progression, and enhancing the overall quality of life in affected children.</p>","PeriodicalId":11968,"journal":{"name":"European Journal of Dermatology","volume":"35 4","pages":"307-312"},"PeriodicalIF":1.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145080014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a case study of erythema multiforme-like drug eruption induced by secukinumab and provide an overview of all cases reported so far. A systematic literature search of publications was conducted from inception to September 2024 via PubMed and Web of Science Core Collection, in order to identify all cases of drug hypersensitivity reactions associated with secukinumab. We conducted a search for retrospective and prospective studies, case series, case reports, and data from Phase II and III clinical trials related to immune-related (or potentially immune-related) adverse events associated with the use of secukinumab. In total, four cases of drug hypersensitivity reactions associated with secukinumab were identified. Drug hypersensitivity reactions associated with secukinumab are relatively rare.
