Parental Decision‐Making and Pregnancy Outcomes After Increased First‐Trimester Nuchal Translucency: A 12‐Year Cohort

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To describe diagnostic trajectories and parental decision‐making following increased first‐trimester nuchal translucency (NT), according to NT thickness. Method This 12‐year retrospective cohort study was conducted at a French tertiary Prenatal Diagnosis and Fetal Medicine Center and included 316 singleton pregnancies with first ...

Structure‐energy‐based predictions and network modelling of RASopathy and cancer missense mutations

open access: yesMolecular Systems Biology, 2014
The Ras/MAPK syndromes (‘RASopathies’) are a class of developmental disorders caused by germline mutations in 15 genes encoding proteins of the Ras/mitogen‐activated protein kinase (MAPK) pathway frequently involved in cancer.

Basal Cell Carcinoma and Syringocystoadenoma Papilliferum Arising in Naevus Sebaceous—A Narrative Review

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Naevus sebaceous (NS) is a congenital cutaneous hamartoma characterised by epidermal, follicular, sebaceous and apocrine components, with a rare but significant potential for malignant transformation, most commonly into basal cell carcinoma (BCC).

Management of rasopathies [PDF]

open access: yesInternational Journal of Pediatric Endocrinology, 2013
Noonan syndrome (NS) and NS-related disorders (Cardio-Facio-Cutaneous (CFC) syndrome, Costello syndrome, LEOPARD (Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth and sensory neural Deafness) syndrome) share common clinical features characterized by unique facial features ...

Clinical and Genetic Profile of One Molecularly Confirmed and One Clinically Suspected Case of LZTR1‐Related Noonan Syndrome

open access: yesClinical Genetics, EarlyView.
This study illustrates the phenotypic variability of LZTR1‐related Noonan syndrome type 10 in two pediatric patients, including presentations without congenital heart defects. The findings emphasize the importance of whole‐exome sequencing and longitudinal re‐evaluation of variants of uncertain significance in achieving accurate diagnosis.

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

open access: yesClinical 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.

Improvement of synaptic plasticity and cognitive function in RASopathies—a monocentre, randomized, double-blind, parallel-group, placebo-controlled, cross-over clinical trial (SynCoRAS)

open access: yesTrials, 2023
Background Cognitive impairment is a common medical issue in rat sarcoma (RAS) pathway disorders, so-called RASopathies, like Neurofibromatosis type 1 (NF1) or Noonan syndrome (NS). It is presumed to be caused by impaired synaptic plasticity.

The Evolving Landscape of CHD Genetics: A Contemporary Guide to Genetic Testing and Management

open access: yesJournal of Paediatrics and Child Health, EarlyView.
ABSTRACT Congenital heart disease (CHD) is the most common birth defect, affecting an estimated 9.4/1000 infants globally. The genetics of CHD is complex, with most cases thought to have multifactorial aetiology, implicating both genetic and environmental factors.

Clinical overview on RASopathies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2022
AbstractRASopathies comprise a group of clinically overlapping developmental disorders caused by genetic variations affecting components or modulators of the RAS‐MAPK signaling cascade, which lead to dysregulation of signal flow through this pathway.

Resolution of Refractory Multifocal Atrial Tachycardia in Costello Syndrome Using Trametinib: A Case Supporting MEK Inhibitors as Targeted, Specific Antiarrhythmic

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 2151-2156, September 2026.
ABSTRACT Arrhythmias affect approximately half of patients with Costello syndrome (CS, OMIM # 218040), with non‐reentrant atrial tachycardia being the most common. This case describes an infant with Costello syndrome carrying the pathogenic HRAS c.34G>A (p.G12S) variant who developed early‐onset, drug‐refractory multifocal atrial tachycardia (MAT ...
