Distinct Xp11.2 breakpoints in two renal cell carcinomas exhibiting X;autosome translocations

1995

Several human renal cell carcinomas with X;autosome translocations have been reported in recent years. The t(X; I)(p11.2;q21) appears to be a specific primary anomaly, suggesting that tumors with this translocation form a distinct subgroup of RCC. Here we report two new cases, one with a t(X;10)(p11.2;q23), the other with a t(X;1)(p11.2;p34). The common breakpoint in Xp11.2 suggests that they belong to the above-mentioned subset of RCC. Using FISH in conjunction with X-specific YAC clones, we demonstrate that the two new cases exhibited distinct breakpoints within Xp11.2. (C) 1995 Wiley-Liss, Inc.

Measurement of the background in the NEMO 3 double beta decay experiment

2009

In the double beta decay experiment NEMO 3 a precise knowledge of the background in the signal region is of outstanding importance. This article presents the methods used in NEMO 3 to evaluate the backgrounds resulting from most if not all possible origins. It also illustrates the power of the combined tracking-calorimetry technique used in the experiment.

Missense mutations in the coagulation factor XII (Hageman factor) gene in hereditary angioedema with normal C1 inhibitor.

2006

Hereditary angioedema is characterized by recurrent skin swelling, abdominal pain attacks, and potentially life-threatening upper airway obstruction. The two classic types are both caused by mutations within the complement C1 inhibitor gene. A recently described new type does not show a deficiency of C1 inhibitor and affects almost exclusively women. We screened twenty unrelated index patients with this new type of hereditary angioedema for mutations in the coagulation factor XII gene. Two different missense mutations were identified in exactly the same position within exon 9 of the F12 gene. 'Mutation 1' (1032C-->A), encountered in five patients, predicts a threonine-to-lysine substitution…

Ankylosing spondylitis: an autoimmune or autoinflammatory disease?

2021

Ankylosing spondylitis (AS) is a chronic inflammatory disease with hallmarks of both autoimmune and autoinflammatory pathology. In this Review, the authors examine the evidence for both disease processes and aim to reconcile the two.Ankylosing spondylitis (AS) is a chronic inflammatory disorder of unknown aetiology. Unlike other systemic autoimmune diseases, in AS, the innate immune system has a dominant role characterized by aberrant activity of innate and innate-like immune cells, including gamma delta T cells, group 3 innate lymphoid cells, neutrophils, mucosal-associated invariant T cells and mast cells, at sites predisposed to the disease. The intestine is involved in disease manifesta…

Comparative multiplex dosage analysis in spinocerebellar ataxia type 2 patients.

2013

We developed a new application of comparative multiplex dosage analysis (CMDA) for evaluation of the ataxin 2 gene. Expansions of the triplet CAG can cause spinocerebellar ataxia type 2 (SCA2), a neurodegenerative disease with an autosomal-dominant mode of inheritance. Molecular diagnosis of SCA2 is routinely based on the use of conventional PCR to detect the CAG expansion. However, PCR does not amplify an allele with an expansion of many triplets (>80), which is typically found in infantile and juvenile forms of SCA2, thus leading to false negatives. We propose the analysis of the ATXN2 gene by CMDA to complement existing methods currently used for the detection of large expansions of the …

Uptake of hysterectomy and bilateral salpingo-oophorectomy in carriers of pathogenic mismatch repair variants:a Prospective Lynch Syndrome Database r…

2021

Purpose: This study aimed to report the uptake of hysterectomy and/or bilateral salpingo-oophorectomy (BSO) to prevent gynaecological cancers (risk-reducing surgery [RRS]) in carriers of pathogenic MMR (path_MMR) variants.Methods: The Prospective Lynch Syndrome Database (PLSD) was used to investigate RRS by a cross-sectional study in 2292 female path_MMR carriers aged 30-69 years.Results: Overall, 144, 79, and 517 carriers underwent risk-reducing hysterectomy, BSO, or both combined, respectively. Two-thirds of procedures before 50 years of age were combined hysterectomy and BSO, and 81% of all procedures included BSO. Risk-reducing hysterectomy was performed before age 50 years in 28%, 25%,…

Hereditary Angioedema: Long-Term Treatment with One or More Injections of C1 Inhibitor Concentrate per Week

2009

<i>Background:</i> Hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH) is characterized by recurrent edema attacks in various organs. The objective of the present study was to assess the efficacy and safety of weekly long-term replacement treatment with one or more injections of plasma-derived C1-INH concentrate per week (WLTC) in patients with HAE-C1-INH. <i>Methods:</i> Nineteen patients with HAE-C1-INH underwent WLTC for 9 years on average. The benefits and risks were determined based on regular recording by the patients of the severity and number of attacks at the beginning and the end of the study. <i>Results:</i> All patients reported …

Further delineation of eye manifestations in homozygous 15q13.3 microdeletions including TRPM1: a differential diagnosis of ceroid lipofuscinosis.

2014

The 15q13.3 heterozygous microdeletion is a fairly common microdeletion syndrome with marked clinical variability and incomplete penetrance. The average size of the deletion, which comprises six genes including CHRNA7, is 1.5 Mb. CHRNA7 has been identified as the gene responsible for the neurological phenotype in this microdeletion syndrome. Only seven patients with a homozygous microdeletion that includes at least CHRNA7, and is inherited from both parents have been described in the literature. The aim of this study was to further describe the distinctive eye manifestations from the analysis in the three French patients diagnosed with the classical 1.5 Mb homozygous microdeletion. Patients…
