Neurofibromatosis (NF), Noonan syndrome (NS), and LEOPARD syndrome are all autosomal dominant conditions, each being a distinct clinical entity by itself. Rarely, one encounters cases with features of NF and NS and is termed as the 'Neurofibromatosis-Noonan syndrome' (NF-NS). The authors report a clinical dilemma with major clinical features of the NF-NS syndrome and LEOPARD syndrome co-existing in the same patient. Also, features of Noonan syndrome and LEOPARD syndrome are compared with the case reported.

A patient with a PTPN11 gene variant complicated with Chiari I malformation and syringomyelia and a review of literatures.
Int J Dev Neurosci
February 2025
Department of Pediatric Neurology, The Affiliated Hospital of Qingdao University, Qingdao, Shandong, China.
Article Synopsis
- PTPN11 gene variants are linked to around 50% of Noonan syndrome and 85% of Leopard syndrome cases, with some patients showing associations with Chiari I malformation (CIM) and syringomyelia, though the nature of this relationship is debated.
- A clinical case was analyzed along with a genetic test on the patient and her family, revealing a specific PTPN11 variant (c. 922A>G) and leading to discussions about the possible connections between these conditions.
- The retrospective review identified six patients with NS or LS and a PTPN11 variant who also exhibited CIM or syringomyelia, highlighting a potential pattern that warrants further investigation.

Introduction: Granular cell tumors (GCT) are predominantly benign neoplasms composed by cells with abundant eosinophilic granular cytoplasm. Although the majority of GCTs exhibit a benign clinical course, a minority display cytological atypia and may exhibit aggressive, cancer-like behavior. Definitive evidence of malignancy in GCTs is reliably established only through the presence of metastasis.

Division of Pediatric Oncology, Johns Hopkins University School of Medicine, Baltimore, MD, United States.
Article Synopsis
- The RASopathies are a group of genetic syndromes caused by mutations in the RAS/MAPK signaling pathway, affecting conditions like neurofibromatosis type 1, Noonan syndrome, and others, often leading to similar symptoms due to abnormal cell growth.
- Epidermal nevus syndromes are characterized by skin nevi alongside other systemic issues, with recent findings indicating that mosaic RAS mutations may contribute to these conditions.
- A case study details a child's treatment with the MEK inhibitor selumetinib, demonstrating stabilization of nerve hypertrophy and improvement of skin lesions, highlighting the potential for targeted therapies beyond currently established uses for RASopathy-related symptoms.
CASE-CONTROL STUDY OF THE FREQUENCY AND ETIOLOGY OF ATAXIA IN ASIATIC LIONS () BETWEEN 2002 AND 2020.

September 2024
Rotterdam Zoo, 3041 JG, Rotterdam, the Netherlands,
Article Synopsis
- The Asiatic lion is an endangered species, and a study assessed neurological issues in captive populations, focusing on signs like ataxia and stargazing.
- The research reviewed medical histories, blood tests, and imaging of 74 lions, revealing a rising prevalence of ataxia over the years, with significant differences in blood results between healthy and affected lions.
- Key findings included abnormalities in the brain and spine similar to those in African lions, suggesting a potential link to vitamin A deficiency, and highlighting the possibility of hereditary factors in these neurological issues.
