Vascular Abnormalties in Neurofibromatosis Type 1

Pediatric Neurology Briefs, 2005
The spectrum of cerebrovascular abnormalities (CVA), including moyamoya, was evaluated in a retrospective chart review of 353 patients with neurofibromatosis type 1 (NF1) seen at the Children’s National Medical Center, Washington, DC, from 1995 to 2003.

A conserved circadian function for the Neurofibromatosis 1 gene [PDF]

, 2018
Summary: Loss of the Neurofibromatosis 1 (Nf1) protein, neurofibromin, in Drosophila disrupts circadian rhythms of locomotor activity without impairing central clock function, suggesting effects downstream of the clock.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

A multicenter study of neurofibromatosis type 1 utilizing deep learning for whole body tumor identification

npj Digital Medicine
Deep-learning models have shown promise in differentiating between benign and malignant lesions. Previous studies have primarily focused on specific anatomical regions, overlooking tumors occurring throughout the body with highly heterogeneous whole-body

Optimizing Diagnostic Accuracy of Clinical Red Flags in RASopathies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are a group of genetic disorders caused by pathogenic variants in the RAS‐mitogen‐activated protein kinase (RAS–MAPK) signaling pathway, often presenting with congenital heart defects, craniofacial dysmorphisms, and developmental delays. To assess the diagnostic yield of genetic testing in patients with suspected RASopathies and to

Ewing sarcoma in a child with neurofibromatosis type 1. [PDF]

, 2019
We report here on a case of Ewing sarcoma (ES) occurring in a child with neurofibromatosis type 1. The sarcoma had an EWSR1-ERG translocation as well as loss of the remaining wild-type allele of NF1. Loss of the NF1 wild-type allele in the tumor suggests

The 9th International RASopathies Symposium

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.
