A rare association of a high grade glioblastoma, cerebral abscess and acute lymphoblastic leukemia in a child with Noonan syndrome
Leuk Res Rep. 2023 Dec 1;21:100404. doi: 10.1016/j.lrr.2023.100404. eCollection 2024.ABSTRACTNoonan syndrome is a genetic disorder frequently caused by PTPN11 mutations. Patients with Noonan syndrome are characterized by facial dysmorphism, short stature and congenital heart defects and they have a reported predisposition to malignancies such as leukemia, and solid and central nervous system tumors. Here, we report a case of a 14-year-old boy with Noonan syndrome treated for T-cell acute lymphoblastic leukemia who presented with 2 concomitant abnormalities: cerebral abscess and high grade glioblastoma. This exceptional ass...

Genes, Vol. 15, Pages 32: A Novel Homozygous Loss-of-Function Variant in SPRED2 Causes Autosomal Recessive Noonan-like Syndrome
o Giulio Piluso Noonan syndrome is an autosomal dominant developmental disorder characterized by peculiar facial dysmorphisms, short stature, congenital heart defects, and hypertrophic cardiomyopathy. In 2001, PTPN11 was identified as the first Noonan syndrome gene and is responsible for the majority of Noonan syndrome cases. Over the years, several other genes involved in Noonan syndrome (KRAS, SOS1, RAF1, MAP2K1, BRAF, NRAS, RIT1, and LZTR1) have been identified, acting at different levels of the RAS-mitogen-activated protein kinase pathway. Recently, SPRED2 was recognized as a novel Noonan syndrome gene with autos...

Adult-onset idiopathic peripheral pulmonary artery stenosis
Extract Peripheral pulmonary artery stenosis (PPS) is defined as the obstruction of the pulmonary artery from the pulmonary artery trunk to the peripheral arteries. PPS is considered a paediatric-onset disease associated with systemic congenital diseases (congenital rubella syndrome, Williams syndrome, Alagille syndrome, Ehlers–Danlos syndrome and Noonan syndrome) [1–4]. Apart from PPS associated with congenital syndromes, adult-onset idiopathic PPS has been reported [5]; however, it is rare and has not been reported in more than 10 cases. Transcatheter pulmonary angioplasty for chronic thromboembolic pulmonary...

Implementation of a Scalable Online Weight Management Programme in Clinical Settings: Protocol for the PROPS 2.0 Programme (Partnerships for Reducing Overweight and Obesity with Patient-Centered Strategies 2.0)
Introduction There is an urgent need for scalable strategies for treating overweight and obesity in clinical settings. PROPS 2.0 (Partnerships for Reducing Overweight and Obesity with Patient-Centered Strategies 2.0) aims to adapt and implement the combined intervention from the PROPS Study at scale, in a diverse cross-section of patients and providers. Methods and analysis We are implementing PROPS 2.0 across a variety of clinics at Brigham and Women’s Hospital, targeting enrolment of 5000 patients. Providers can refer patients or patients can self-refer. Eligible patients must be ≥20 years old and have a body m...

SHP2 clinical phenotype, cancer, or RASopathies, can be predicted by mutant conformational propensities
Cell Mol Life Sci. 2023 Dec 12;81(1):5. doi: 10.1007/s00018-023-05052-8.ABSTRACTSHP2 phosphatase promotes full activation of the RTK-dependent Ras/MAPK pathway. Its mutations can drive cancer and RASopathies, a group of neurodevelopmental disorders (NDDs). Here we ask how same residue mutations in SHP2 can lead to both cancer and NDD phenotypes, and whether we can predict what the outcome will be. We collected and analyzed mutation data from the literature and cancer databases and performed molecular dynamics simulations of SHP2 mutants. We show that both cancer and Noonan syndrome (NS, a RASopathy) mutations favor catalys...
