INTRODUCTION AND OBJECTIVES Cardiomyopathy and channelopathy are major causes of sudden death (SD). The little information available on the context in which SD occurs has come from only a few referral centers. The objective was to investigate the circumstances surrounding SD in families with inherited heart disease. METHODS The study included 152 SD patients (mean age 43+/-19 years) from 103 ...

Brugada syndrome (BS) is a genetic channelopathy, clinically characterized by an increased risk of sudden cardiac death. The diagnosis requires typical electrocardiographic pattern, and data on stratification are limited in the literature. aim this study was to conduct review importance exercise stress test (EST) BS. Articles were searched PubMed, Scielo Google Scholar databases. From 200 artic...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), caused by dominant mutations in the NOTCH3 receptor in vascular smooth muscle, is a genetic paradigm of small vessel disease (SVD) of the brain. Recent studies using transgenic (Tg)Notch3(R169C) mice, a genetic model of CADASIL, revealed functional defects in cerebral (pial) arteries on the sur...

Autism spectrum disorder (ASD) is a syndrome that affects normal brain development and is characterized by impaired social interaction as well as verbal and non-verbal communication and by repetitive, stereotypic behavior. ASD is a complex disorder arising from a combination of multiple genetic and environmental factors that are independent from racial, ethnic and socioeconomical status. The hi...

INTRODUCTION Long QT-syndrome (LQTS) is a genetic cardiac channelopathy characterised by a prolonged QT interval on a surface electrocardiogram (ECG), syncope, T-wave abnormalities, ventricular tachycardia of the torsades de pointes (TdPVT) type (Fig. 1) and an increased risk of sudden death [1]. LQTS has variable clinical presentation and is genetically characterised by incomplete penetrance, ...

Clinical abnormalities in multiple sclerosis (MS) have traditionally been attributed to inflammation, demyelination, or degeneration of axons within the brain and spinal cord. Among those symptoms, clinical deficits due to cerebellar dysfunction, including loss of coordination, ataxia, tremor, and dysarthria, can reduce function substantially, are less likely to remit, and are more likely to be...
