Abstract:
Background: Common variable immunodeficiency (CVID) is a term used to define a heterogeneous group of patients who commonly have hypogammaglobulinemia and variable degrees of modest T cell dysfunction. Recent advances made in next generation sequencing technologies have accelerated the identification of CVID disease-causing genes, including NFKB1, a component of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. Objective: We sought to identify the genetic defect in a 3-generation family of patients with CVID who presented with cytopenias, eczema, and recurrent

Abstract:
Tuberous sclerosis (TSC) is a single-gene disorder caused by heterozygous mutations in either the TSC1 or TSC2 genes (Consortium, 1993; van Slegtenhorst et al., 1997). In 70% of cases, TSC gene mutations arise de novo. The remaining 30% of cases are familial with an autosomal dominant pattern of inheritance. Tuberous sclerosis belongs to the group of phakomatoses (neurocutaneous disorders) and is associated with characteristic manifestations in various organ systems, including the brain, skin, kidney, lung, heart, and liver (Crino, Nathanson, & Henske, 2006; Curatolo, Bombardieri & Joz

Abstract:
Long QT syndrome(s) (LQTS) includes a group of inherited arrhythmogenic disorders characterized by a prolonged cardiac repolarization that predisposes to the development of life-threatening arrhythmias, typically in conditions of adrenergic activation (exercise, emotions). LQTS can show both autosomal dominant and autosomal recessive transmission with variable penetrance. Several genes have been causally linked to the disease phenotype, all coding for ion channel proteins and their regulatory partners that control cardiac action potentials duration. To date, 17 genes have been identified. Still, the first three genotypes discovered in the early nineties (LQT1, LQT2, and LQT3) account for the large majority of mutation-positive cases (approximately 80–90%). Genotype-negative LQTS subjects still represent an area of investigation: large duplications and deletions, undetectable to standard screening methodologies and, more recently, polygenic inheritance and the role of modifiers are emerging as possible players for (apparently) genotype-negative LQTSx1. Knowing the genotype of a LQTS patient can provide a relevant contribution for the clinical management by supporting the diagnostic process, the risk stratification, and the choice of therapy.

Abstract:
Arrhythmogenic cardiomyopathy is a rare genetic entity characterized by progressive fibro-fatty replacement of myocardium leading to malignant arrhythmias, syncope, and sudden cardiac death. Mostly it affects the right ventricle, but cases have also been described with biventricular and even isolated left ventricular involvement. The disease affects mainly young males and arrhythmias are usually induced by exercise. Arrhythmogenic cardiomyopathy has a genetic origin and is basically caused by deleterious alterations in genes encoding desmosomal proteins, especially plakophilin-2. To date, more than 400 rare genetic alterations have been identified in 18 genes, mainly with autosomal dominant inheritance, but some recessive forms have also been reported (Naxos disease and Carvajal syndrome). A comprehensive genetic analysis identifies a rare variant as potential cause of the disease in around 60% of patients, suggesting the existence of unknown genes as well as other genome alterations not yet discovered. Genetic interpretation classifies some of these rare variants as ambiguous, playing an uncertain role in arrhythmogenic cardiomyopathy. This makes a proper translation of genetic data into clinical practice difficult. Moreover, incomplete penetrance and variable phenotypic expression makes it difficult to arrive at the correct diagnosis. In the present chapter, we focus on recent advances in the knowledge regarding the genetic basis of arrhythmogenic cardiomyopathy.

Abstract:
The heritable arrhythmogenic disorder Brugada syndrome (BrS), a cardiac ion channelopathy first described in 1992, is inherited as an autosomal dominant trait characterized by incomplete penetrance, variable expression, and phenotypic overlap. These characteristics all complicate the elucidation of the underlying molecular genetic pathway. Clearly, SCN5A, the gene encoding the pore-forming alpha subunit of the cardiac sodium channel, is the major susceptibility gene associated with BrS: 20–30% of BrS patients harbour pathogenic variants in this gene and BrS patients have a more than eight times higher burden of rare variants in this gene compared to controls. Rare pathogenic variants have also been reported in several sodium, potassium, and calcium channel genes, pacemaker genes, and sodium channel interacting genes. Given the minor collective contribution of these additional BrS-associated genes to the total genetic diagnostic yield, the hypothesis has been raised that other (genetic) determinants are involved. Indeed, the monogenic nature of BrS has been questioned and more support has recently been gained for the hypothesis of a complex inheritance based on genome-wide and gene panel studies. Probably, the BrS inheritance pattern is a continuum ranging from a monogenic, over an oligogenic towards even a polygenic spectrum. This, however, further impedes the interpretation of the contribution of (likely) pathogenic variants to the phenotype and urges for a cautious policy in a prenatal and preimplantation genetic diagnostic context: in many cases disease prevention will imply a risk reduction instead of an elimination of disease (development).

Often, the analysis is done by using FEA (Finite Element Analysis) to include the compliant behavior of the parts. There are many variables that affect the geometric quality and to include many of them in a FEA simulation is often very time-consuming. One way of performing the simulations relat

Therefore, large allowances must be made when assessing the integrity of this pipe work to this failure mechanism.
