Genetic Spectrum of Non‐PTPN11 Variants in Noonan Syndrome and Related RASopathies: Findings From a Russian Cohort

Clinical Genetics, EarlyView.
Noonan syndrome and related conditions are caused by variants in multiple genes. We analyzed 456 Russian patients using a 23‐gene panel and found disease‐causing variants in non‐PTPN11 genes in 85 cases. NF1, SOS1, BRAF, and SHOC2 explained half of these diagnoses.

Accelerated long‐term forgetting in children with neurofibromatosis type 1

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To investigate the presence of accelerated long‐term forgetting after a 7‐day delay in children with neurofibromatosis type 1 (NF1), using an adapted verbal memory recall task, Experimental Word Recall Task (EWRT), and to examine its relationship with other cognitive abilities.

Neurofibromatosis Type 1 and Sporadic Optic Gliomas

Pediatric Neurology Briefs, 2002
The natural history of sporadic optic gliomas was compared with that of optic gliomas associated with neurofibromatosis type 1 (NF1) in a study using a Children’s Tumor Registry (CTR) and an NF1 Database (NF1DB) at St Mary’s Hospital, Manchester, UK.

A Practical Guide to Chromosome Microarray Interpretation for Paediatricians

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Introduction Chromosome microarray (CMA) is a test commonly ordered by general paediatricians. It has diagnostic yield between 10%–15% in individuals with neurodevelopmental delay, autism and/or multiple congenital abnormalities. CMA identifies copy number variants (CNV) including deletions and duplications, which may be pathogenic, variants ...

Establishing the diagnosis neurofibromatosis type 1: A rare case

Dermatology Reports, 2019
Neurofibromatosis type 1 (NF1) or Von Recklinghausen's disease is a dominantly inherited genetic, multisystem disorder. Individuals with neurofibromatosis type 1 are prone to develop benign and malignant tumors of the CNS and peripheral nervous system ...

Somatic neurofibromatosis type 1 (NF1) inactivation characterizes NF1-associated pilocytic astrocytoma [PDF]

Genome Research, 2012
Low-grade brain tumors (pilocytic astrocytomas) arising in the neurofibromatosis type 1 (NF1) inherited cancer predisposition syndrome are hypothesized to result from a combination of germline and acquired somaticNF1tumor suppressor gene mutations. However, genetically engineered mice (GEM) in which mono-allelic germlineNf1gene loss is coupled with bi ...

Periodontal Disease and Salivary Gland Dysfunction in Neurofibromatosis Type 1: A Case–Control Study

Oral Diseases, EarlyView.
ABSTRACT Objectives Neurofibromatosis type 1 (NF1) presents with diverse systemic and oral manifestations. The aim of this study was to investigate the periodontal status and salivary alterations in NF1 individuals. Methods A total of 38 individuals with NF1 diagnostic criteria were compared with a control group paired by age and sex.

The WHO Classification of Genetic Tumour Syndromes: Considerations for Genetics

Clinical Genetics, Volume 110, Issue 3, Page 389-401, September 2026.
The WHO Classification of Tumours underpins the diagnosis of neoplastic conditions. The new WHO classification of genetic tumour syndromes (GTS) provides international standards for their diagnosis. This diagram highlights the chromosomal distribution of the genes involved in the GTS covered in this classification.

Learning disability and oligodendrocyte myelin glycoprotein (OMGP) gene in neurofibromatosis type 1

The Turkish Journal of Pediatrics, 2011
Neurofibromatosis type 1 (NF1) is an autosomal dominant disease where phenotypic heterogeneity is explained by the effect of modifier genes. Thirty to 65% of patients have learning disability.
