Noonan syndrome is the second most common syndromic cause of congenital heart disease. 50-70% of individuals with NS are born with some form of congenital heart defect, with pulmonary valvular stenosis being the most common (50–60%). [9]
Sick sinus syndrome: Taussig–Bing syndrome: double outlet right ventricle (DORV) and subpulmonic VSD. a cyanotic congenital heart defect: Timothy syndrome: Townes–Brocks syndrome: Triploid syndrome: Turner syndrome: VACTERL syndrome: Wellens' syndrome: Williams syndrome: Wolff–Parkinson–White syndrome: A Delta wave often seen in an ...
Jacqueline Anne Noonan (October 28, 1928 – July 23, 2020) was an American pediatric cardiologist best known for her characterization of a genetic disorder now called Noonan syndrome. [ 1 ] [ 2 ] She was also the original describer of hypoplastic left heart syndrome .
Most congenital heart defects are not associated with other diseases. [3] A complication of CHD is heart failure. [2] Congenital heart defects are the most common birth defect. [3] [11] In 2015, they were present in 48.9 million people globally. [8] They affect between 4 and 75 per 1,000 live births, depending upon how they are diagnosed.
Noonan syndrome with multiple lentigines (NSML) which is part of a group called Ras/MAPK pathway syndromes, [2] is a rare autosomal dominant, [3] multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene . The disease is a complex of features, mostly involving the skin, skeletal and cardiovascular ...
Atrioventricular septal defect (AVSD) or atrioventricular canal defect (AVCD), also known as "common atrioventricular canal" or "endocardial cushion defect" (ECD), is characterized by a deficiency of the atrioventricular septum of the heart that creates connections between all four of its chambers. It is a very specific combination of 3 defects:
Legius syndrome, also known as NF1-like syndrome; Noonan syndrome with multiple lentigines (NSML), formerly called LEOPARD syndrome; SYNGAP1-related intellectual disability; Somatic mutations in the Ras/MAPK pathway can cause cancers and disorders such as RAS-associated autoimmune leukoproliferative disorder (RALD) or juvenile myelomonocytic ...
Because the heartbeat is dependent on the proper movement of ions across the surface membrane, cardiac channelopathies make up a key group of heart diseases. [3] Long QT syndrome, the most common form of cardiac channelopathy, is characterized by prolonged ventricular repolarization, predisposing to a high risk of ventricular tachyarrhythmias ...
