"Incidence and Consequences of Disorders of Glycosylation in Patients With Conotruncal and Septal Heart Defects"

2015-07-22 11:37:42 | BioPortfolio

Summary

The objective of the study is to investigate congenital disorders of glycosylation in congenital heart diseases without a clear molecular or genetic basis.

Description

Congenital disorders of glycosylation (CDG) are a family of inherited disorders caused by defects in the synthesis of glycans, glycoproteins or other glycoconjugates. Congenital disorders of glycosylation (CDG) are a family of inherited disorders caused by defects in the synthesis of glycans, glycoproteins or other glycoconjugates. Glycosylation of proteins is crucial for a proper organ morphogenesis and for an appropriate coagulation system functioning. The neurological system is commonly affected in this type of disorders but cases of CDG with normal neurological development have been recently described. The group of Experimental Hematology and Clinic Oncology of the University of Murcia (Spain) recently described a rare disorder of glycosylation (ALG12-CDG) as the cause of antithrombin deficiency in a patient of 19 years with a history of repaired ventricular septal defect.

On the other hand, population studies have shown an increased incidence of thromboembolic events in patients with congenital heart disease when compared to the general population. The identified genetic defects involved in the development of congenital heart diseases have variable or incomplete penetrance and in most cases the molecular basis is completely unknown.

The investigators postulate that a CDG might be behind the development of some forms of congenital heart disease and contribute to the greater prevalence of thromboembolic events in this patient population.

Medical and Biotech [MESH] Definitions

Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.

Inflammation of the ENDOCARDIUM caused by BACTERIA that entered the bloodstream. The strains of bacteria vary with predisposing factors, such as CONGENITAL HEART DEFECTS; HEART VALVE DISEASES; HEART VALVE PROSTHESIS IMPLANTATION; or intravenous drug use.

Diseases existing at birth and often before birth, or that develop during the first month of life (INFANT, NEWBORN, DISEASES), regardless of causation. Of these diseases, those characterized by structural deformities are termed CONGENITAL ABNORMALITIES.

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.

Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144.
