Colon cancer in a patient with a mosaic monoallelic germline pathogenic NF1 gene variant [PDF]

Exploration of Neuroscience
Pathogenic variants in the tumor suppressor gene NF1 cause neurofibromatosis type 1 (NF1), one of the most common hereditary cancer predisposition syndromes. Pathogenic NF1 variants have been associated with an increased risk of several cancers; however,

Cerebellum-dependent associative learning is not impaired in a mouse model of neurofibromatosis type 1

Scientific Reports, 2022
Individuals with Neurofibromatosis type 1 (NF1) experience a high degree of motor problems. The cerebellum plays a pivotal role in motor functioning and the NF1 gene is highly expressed in cerebellar Purkinje cells.

Identification and characterization of NF1 and non-NF1 congenital pseudarthrosis of the tibia based on germline NF1 variants: genetic and clinical analysis of 75 patients

Orphanet Journal of Rare Diseases, 2019
Background Congenital pseudarthrosis of the tibia (CPT) is a rare disease. Some patients present neurofibromatosis type 1 (NF1), while some others do not manifest NF1 (non-NF1). The etiology of CPT, particularly non-NF1 CPT, is not well understood.

Congenital anomalies in neurofibromatosis 1: a retrospective register-based total population study

Orphanet Journal of Rare Diseases, 2018
Background Neurofibromatosis type 1 (NF1) is a dominantly inherited Rasopathy caused by mutations in the NF1 gene on chromosome 17. NF1 has been connected to congenital anomalies, e.g., in the skeletal and cardiovascular systems, but the overall ...

Unilateral Yasunari nodule-like appearance in a patient without neurofibromatosis type 1

European Journal of Case Reports in Internal Medicine
Introduction: Yasunari nodules are choroidal lesions characterized by bright, poorly demarcated multiple lesions detected through near-infrared reflectance imaging and are considered diagnostic for neurofibromatosis type 1 (NF1).
