Complex Genetic Architecture in RASopathies: Constitutional PTPN11 and Mosaic RIT1 Pathogenic Variants Underlying Severe Noonan Syndrome With Adult‐Onset Acute Myeloid Leukemia

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome (NS) is a genetically heterogeneous disorder characterized by a broad spectrum of clinical features resulting from dysregulation of the RAS/MAPK pathway. Although complex genotypes are increasingly recognized in NS, cases harboring two distinct pathogenic variants in different NS genes remain extremely rare.

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

American Journal of Medical Genetics Part A, EarlyView.
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 ...
