Patients with 22q11 deletion syndrome (22q11.2DS) present, in about 75% of cases, typical patterns of cardiac defects, with a particular involvement on the ventricular outflow tract and great arteries. However, in this genetic condition the dimensions of the pulmonary arteries (PAs) never were specifically evaluated. We measured both PAs diameter in patients with 22q11.2DS without cardiac defects, comparing these data to a normal control group. Moreover, we measured the PAs diameter in Tbx1 mutant mice. Finally, a cell fate mapping in Tbx1 mutants was used to study the expression of this gene in the morphogenesis of PAs.

Anomalous origin of the left pulmonary artery (ALPA) from the aorta is a rare form of congenital heart disease, leading to long-term morbidity if not treated early. There is a reported association of ...
The 22q11.2 Deletion Syndrome (22q11.2DS) occurs in ~1:3,000-6,000 individuals. Features less typically associated with 22q11.2DS, such as orthopedic manifestations, may be overlooked or may not lead ...
A case of clinically unsuspected fatal interrupted aortic arch (IAA) is described. A 17-day-old Japanese girl unexpectedly entered respiratory arrest at home. On autopsy, the heart was hypertrophic, w...
The 22q11.2 deletion syndrome (22q11.2DS) is a congenital malformation and neuropsychiatric disorder caused by meiotic chromosome rearrangements. One of the goals of this review is to summarize the cu...
The 22q11.2 deletion syndrome is caused by non-allelic homologous recombination events during meiosis between low copy repeats (LCR22) termed A, B, C, and D. Most patients have a typical LCR22A-D (AD)...
The purposes of this study are to: 1. study the nature and longitudinal course of psychiatric symptoms in children with the 22q11.2 deletion syndrome and 2. identify genes...
This study is being conducted to develop and evaluate a cell-free fetal DNA test (Ariosa Test) for non-invasive prenatal detection of 22q11.2 chromosomal deletion or duplication.
22q11.2 deletion syndrome is a genetic disorder that can cause heart defects, facial abnormalities, and developmental and learning disabilities. The severity of the disorder can vary widel...
Background: The present study aims to identify the mechanisms underlying the deficit in facial emotion recognition reported both in schizophrenia and the 22q11.2 deletion syndrome, and th...
This randomized withdrawal study will evaluate the safety and efficacy of NFC-1 in subjects aged 12-17 years with 22q11.2 deletion syndrome and commonly associated neuropsychiatric conditi...
Condition with a variable constellation of phenotypes due to deletion polymorphisms at chromosome location 22q11. It encompasses several syndromes with overlapping abnormalities including the DIGEORGE SYNDROME, VELOCARDIOFACIAL SYNDROME, and CONOTRUNCAL AMOMALY FACE SYNDROME. In addition, variable developmental problems and schizoid features are also associated with this syndrome. (From BMC Med Genet. 2009 Feb 25;10:16) Not all deletions at 22q11 result in the 22q11deletion syndrome.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
An anomalous pulmonary venous return in which the right PULMONARY VEIN is not connected to the LEFT ATRIUM but to the INFERIOR VENA CAVA. Scimitar syndrome is named for the crescent- or Turkish sword-like shadow in the chest radiography and is often associated with hypoplasia of the right lung and right pulmonary artery, and dextroposition of the heart.
A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
Congenital syndrome characterized by a spectrum of malformations including the absence of the THYMUS and PARATHYROID GLANDS resulting in T-cell immunodeficiency and HYPOCALCEMIA. Other features include defects in the outflow tract of the HEART and craniofacial anomalies (velocardiofacial syndrome). Most cases result from a deletion of chromosome 22q11.2 or mutation in the TBX1 gene.
