Noonan syndrome is associated with enhanced pERK activity, the repression of which can prevent craniofacial malformations

Noonan syndrome is associated with enhanced pERK activity, the repression of which can prevent craniofacial malformations.

A gain of function mutation in SHP2, a protein phosphatase encoded by PTPN11, causes Noonan syndrome (NS), which is characterized in part by developmental deficits in both the cardiac and skull fields. Previously, we found that expression of the mutated protein SHP2 Q79R in the heart led to a phenotypic presentation that mimicked some aspects of NS and that this was dependent upon activation of...

Effective palliation of intractable bleeding from Noonan syndrome-associated lymphatic malformations by radiotherapy.

Vitamin D Deficiency is Associated with the Metabolic Syndrome in Subjects with Type 2 Diabetes

Background and Objectives: There is convincing evidence that subjects concomitantly affected by type 2 diabetes (T2D) and metabolic syndrome (MeS) are at greater risk for cardiovascular disease (CVD). Many metabolic derangements in T2D might be attributed to poor vitamin D status. The purpose of this study was to investigate the associations among vitamin D status, MeS and glycemic status in su...

Neurofibromatosis 1/Noonan syndrome associated with Hashimoto's thyroiditis and vitiligo.

Sir, Neurofibromatosis 1 (NF1) is an autosomal dominant disease which predominantly involves the skin and the nervous system. The cardinal features of NF1 include neurofibromas, café-au-lait spots, axillary and inguinal freckling, eye abnormalities comprising Lisch nodules, optic glioma and osseous lesions and learning disabilities (1). Noonan syndrome (NS), is a genetic disorder whose prevelan...

Goldenhar syndrome associated with various cardiovascular malformations.

This report presents a 54-year-old woman with Goldenhar syndrome featuring an epibulbar dermoid, left microtia and a left preauricular appendage, and synostosis of the vertebrae. Multiple cardiovascular malformations including Wolff-Parkinson-White syndrome, a partial anomalous pulmonary venous connection, patent ductus arteriosus, an anomalous origin of the coronary arteries, and a right-sided...
