The classic triad of features of DGS on presentation is conotruncal cardiac anomalies,hypoplasticthymus, and hypocalcemia, and they are diagnosed in early life. However, the phenotype is quite variable , and there may be marked differences between affect...

1996年Daw等[8]报道发现了第2个位于染色体10p13-14的引起DGS/VCFS样表现的位点(DiGeorge syndrome/velo-cardio-facial syndrome complex-2,OMIM 601362),具体致病基因尚不明确。 二、遗传病理机制 染色体22q11.2区域基因组结构复杂,包含至少4个低拷贝重复序列(low copy repeats,LCRs)组成的多重复元件块(several la...

Varied physical defects such as cardiac anomalies, cleft palate, etc., can be corrected via surgery. Hearing aids can help overcome problems with the ear. Different kinds of social, language, emotional, and behavioral problems can be remedied via diverse therapies such as speech therapy, occupation...
The velocardiofacial syndrome is an autosomal dominant disorder characterized by cleft palate, cardiac anomalies, characteristic facies, and learning disabilities. The Di George anomaly involves developmental defects of the third and fourth pharyngeal pouches, resulting in thymic and parathyroid hypoplasia an...
The manifestations of this syndrome cross all medical specialties, and care of the children and adults can be complex. Many patients have a mild to moderate immune deficiency, and the majority of patients have a cardiac anomaly. Additional features include renal anomalies, eye an...
Cardiopharyngeal mesoderm associated with the developing foregut or pharynx contains common heart and head muscle progenitor cells and perturbation of this developmental field results in a spectrum of cardiac and craniofacial congenital anomalies, typified by DiGeorge or 22q11.2 deletion syndrome. These ...
Several of the anomalies found in the MRKH syndrome are also within the clinical spectrum of the 22q11.2 deletion syndrome, also referred to as DiGeorge syndrome (DGS syndrome; OMIM 188400) and velocardiofacial syndrome (VCF syndrome; OMIM 192430). Indeed, this phenotype involves congenital ...
