Fibrinogen is a highly pleiotropic protein that is involved in the final step of the coagulation cascade, wound healing, inflammation, and angiogenesis. Heterozygous mutations in Aα, Bβ, or γ fibrinogen-chain genes (FGA, FGB, FGG) have been described as being responsible for fibrinogen deficiencies (hypofibrinogenemia, hypo-dysfibrinogenemia, dysfibrinogenemia) and for more rare conditions, such as fibrinogen storage disease and hereditary renal amyloidosis. Instead, biallelic mutations have been associated with afibrinogenemia/severe hypofibrinogenemia, i...

The scientific advances in the past few years have enabled individualized prevention and treatment of diseases on the basis of genome-wide information. For example, dozens of genomic regions affecting the risk for coronary artery disease have been identified. Both Finnish and international longitudinal studies show that the risk assessment of coronary artery disease can be significantly improved if the estimate is based both on the newly discovered hereditary risk factors and the long-recognized traditional risk factors, e...

BACKGROUND: Psoriasis is an immune-mediated, inflammatory and hyperproliferative disease of the skin and joints. The cause of psoriasis is still unknown. The fundamental feature of the disease is the hyperproliferation of keratinocytes and the recruitment of cells from the immune system in the region of the affected skin, which leads to deregulation of many well-known gene expressions. OBJECTIVE: Based on data mining and bioinformatic scripting, here we show a new dimension of the effect of psoriasis at the genomic level...

Phaeochromocytoma and paraganglioma (PHEO/PGL) are rare tumours with an estimated annual incidence of 3 per million. Advances in molecular understanding have led to the recognition that at least 30-40% arise in the setting of hereditary disease. Germline mutations in the succinate dehydrogenase genes SDHA, SDHB, SDHC, SDHD and SDHAF2 are the most prevalent of the more than 19 hereditary genetic abnormalities which have been reported. It is therefore recommended that, depending on local resources and availability, at least some degree of genetic testing should be offered to all PHEO/PGL patients, including those with clinically sporadic disease...

REVIEW
Anthony J Gill
The succinate dehydrogenase (SDH) complex is a key respiratory enzyme composed of four subunits: SDHA, SDHB, SDHC and SDHD. Remarkably, immunohistochemistry for SDHB becomes negative whenever there is bi-alleic inactivation of any component of SDH, which is very rare in the absence of syndromic disease. Therefore, loss of SDHB immunohistochemistry serves as a marker of syndromic disease, usually germline mutation of one of the SDH subunits. Tumours which show loss of SDHB expression are termed succinate dehydrogenase-deficient...

BACKGROUND: Postmortem genetic testing for heritable cardiovascular (CV) disorders is often lacking because ideal specimens (ie, whole blood) are not retained routinely at autopsy. Formalin-fixed paraffin-embedded tissue (FFPET) is ubiquitously collected at autopsy, but DNA quality hampers its use with traditional sequencing methods. Targeted next-generation sequencing may offer the ability to circumvent such limitations, but a method has not been previously described. The primary aim of this study was to develop and evaluate the use of FFPET for heritable CV disorders via next-generation sequencing...

Non-classical Ferroportin Disease is a form of hereditary hemochromatosis caused by mutations in the iron transporter ferroportin (Fpn), resulting in parenchymal iron overload. Fpn is regulated by the hormone hepcidin, which induces Fpn endocytosis and cellular iron retention. We characterized 11 clinically-relevant and 5 nonclinical Fpn mutations using stably transfected, inducible, isogenic cell lines. All clinical mutants were functionally resistant to hepcidin as a consequence of either impaired hepcidin binding or impaired hepcidin-dependent ubiquitination despite intact hepcidin binding...

Li-Fraumeni syndrome (LFS) is a hereditary cancer predisposition syndrome, with the characteristics of early onset of cancer and high cancer incidence. TP53 is widely accepted as a pathogenic gene of LFS. A 2 years and 6 months old boy is reported in this article, who was diagnosed with embryonal rhabdomyosarcoma (RMS) in the left submandibular region. His brother died of RMS, and his grandmother was diagnosed with breast cancer. TP53 gene mutation detection was performed in this patient and some family members, indicating a missense mutation in exon 8 of the patient: c...

The non-lysosomal glucosylceramidase GBA2 catalyzes the hydrolysis of glucosylceramide to glucose and ceramide. Loss of GBA2 function results in accumulation of glucosylceramide. Mutations in the human GBA2 gene have been associated with hereditary spastic paraplegia (HSP) and autosomal-recessive cerebellar ataxia (ARCA). Patients suffering from these disorders exhibit impaired locomotion and neurological abnormalities. GBA2 mutations found in these patients have been proposed to impair GBA2 function. However, the molecular mechanism underlying the occurrence of mutations in the GBA2 gene and the development of locomotor dysfunction is not well-understood...

Background: An interval colorectal cancer is a cancer diagnosed prior to the recommended follow-up time from a previously negative colonoscopy. These cancers are thought to arise from a rapidly growing cancer, missed cancer, or incompletely resected adenomas. Our study aimed to identify interval cancers diagnosed during a 4-year period and to identify any potential risk factors associated with these cancers. Secondly, we compared our interval colorectal cancer rate with other published rates...

BRCA genes are important for the integrity and stability of genetic material and play key roles in repairing DNA breaks via high fidelity homologous recombination. BRCA mutations are known to predispose carriers to gynecological malignancies, accounting for a majority of hereditary OC cases. Known to be lethal, OC is difficult to detect and control. Testing for BRCA mutations is a key step in the risk assessment, prognosis, treatment and prevention of OC and current clinical guidelines recommend BRCA mutation testing for all OCs of epithelial origin...

Hereditary angioedema (HAE) with C1-inhibitor deficiency (C1-INH-HAE) is a rare bradykinin-mediated disease characterized by recurrent subcutaneous and/or submucosal angioedematous attacks (HAE attacks), which occur unpredictably. The recurrent HAE attacks do not respond to conventional treatments, and may evolve into a life-threatening condition; therefore, special therapy is required. Areas covered: The agents used so far for the acute management of HAE attacks act by blocking the release of bradykinin, or its binding to its receptor...

FAM134B (family with sequence similarity 134, member B) / RETREG1 and its functional roles are relatively new in human diseases. This review aimed to summarize various functions of FAM134B since our first discovery of the gene in 2001. The protein encoded by FAM134B is a reticulophagy receptor that regulates turnover of the endoplasmic reticulum (ER) by selective phagocytosis. Absence or non-functional expression of FAM134B protein impairs ER-turnover and thereby is involved in the pathogenesis of some human diseases...

The introduction of high throughput sequencing (HTS) techniques greatly improved the knowledge of inherited thrombocytopenias (ITs) over the last few years. A total of 33 different forms caused by molecular defects affecting at least 32 genes have been identified; along with the discovery of new disease-causing genes, pathogenetic mechanisms of thrombocytopenia have been better elucidated. Although the clinical picture of ITs is heterogeneous, bleeding has been long considered the major clinical problem for patients with IT...

DJ-1 is a conserved, ubiquitous protein associated to a large number of intracellular processes. Human DJ-1 has been linked to several pathologies, including hereditary forms of Parkinson's disease, cancer, and amyotrophic lateral sclerosis. Several cytoprotective functions of DJ-1 have been reported, however, its actual mechanisms of action remain elusive. In vitro, DJ-1 has been shown to bind zinc and copper(II) at its active site, which contains a conserved cysteine (C106), and copper(I) at a different binding site...

Official mortality statistics provide population-based data and serve to improve epidemiological knowledge of rare diseases (RDs), by helping with the description of the natural history of the disease. They are an important complement of registries and estimates of disease burden and costs. At the same time, they heighten both the visibility of these diseases and the interest in their study and the search for treatments that may increase survival. This chapter contains a European analysis of hereditary ataxia mortality, which considers the time trend in different countries and the geographical variability in risk of death...
