Abstract LB-382: Identification of predisposing genes for small bowel adenocarcinoma by exome sequencing

2018

Abstract Small bowel adenocarcinoma (SBA) is a rare but aggressive cancer type with limited treatment options. Known predisposing factors include Crohn's disease, celiac disease, and hereditary syndromes such as familial adenomatous polyposis (FAP), Lynch syndrome, and Peutz-Jeghers syndrome. Here, our aim was to further characterize genetic susceptibility to SBA in a large population-based cohort and simultaneously demonstrate the ability to utilize tumor-only data to cost-effectively but reliably call germline variants. Information on all SBAs diagnosed in Finland between the years 2003-2011 were collected utilizing the Finnish Cancer Registry that maintains a nation-wide database on all …

Familial combined hypolipidemia due to mutations in the ANGPTL3 gene

2013

The role of ANGPTL3 in lipoprotein metabolism emerged from studies in a mutant mouse strain characterized by severe hypotriglyceridemia and carrying a loss-of-function (LOF) mutation of the ANGPTL3 gene. ANGPTL3 was found to inhibit lipoprotein lipase and endothelial lipase. Genome-wide association studies in humans demonstrated the association of ANGPTL3 variants with plasma triglyceride levels and LOF mutations of ANGPTL3 were found in hypotriglyceridemic subjects in population studies. Recently, individuals originally classified as affected by familial hypobetalipoproteinemia were found to be homozygotes/compound heterozygotes for rare LOF mutations of ANGPTL3. They show a striking reduc…

Genotypic and phenotypic characterization of patients with autosomal dominant hypercholesterolemia in sicily

2017

Aim: Autosomal dominant hypercholesterolemia (ADH) is an autosomal dominant disorder characterized by high serum low density lipoproteincholesterol (LDL-C) levels. The clinical manifestations of ADH might vary among affected subjects and the phenotype correlates with the severity of mutation and the specific gene involved. The aim of this study was to evaluate the clinical expression and clinical outcomes in a cohort of ADH subjects. Methods: 300 ADH probands with a DUTCH score > 6 were enrolled in this study and the analysis was extended to the family members of these index cases. Anthropometric measures, clinical and biochemical parameters, life style (smoker and/or alcohol habits) and…

Analysis of sequence variations in the LDL receptor gene in Spain: general gene screening or search for specific alterations?

2006

Abstract Background: Familial hypercholesterolemia (FH) is a frequent form of autosomal-dominant hypercholesterolemia that predisposes to premature coronary atherosclerosis. FH is caused by sequence variations in the gene coding for the LDL receptor (LDLR). This gene has a wide spectrum of sequence variations, and genetic diagnosis can be performed by 2 strategies. Methods: Point variations and large rearrangements were screened along all the LDLR gene (promoter, exons, and flanking intron sequences). Results: We screened a sample of 129 FH probands from the Valencian Community, Spain, and identified 54 different LDLR sequence variations. The most frequent (10% of cases) was 111insA, and 60…

Misdiagnosis of familial Mediterranean fever in patients with Anderson-Fabry disease

2012

Fabry disease (FD) is an underdiagnosed pathology due to its symptomatology that overlaps with various systemic and rheumatic disorders, including familial Mediterranean fever (FMF). We examined the Mediterranean fever (MEFV) and α-galactosidase A (GLA) genes, whose mutations are responsible for FMF and FD, respectively, in 42 unrelated patients diagnosed with FMF, which revealed significant ambiguity regarding some of the symptoms which are also present in FD. The objective of this study was to determine the spectrum of mutations present in these genes, in order to identify cases of mistaken diagnosis of FMF and/or missed diagnosis of FD. Ten out of 42 patients had one mutation in homozygo…

Familial hypobetalipoproteinemia: Analysis by next generation sequencing and identification of a novel frameshift mutation in the apoB gene

Mitochondrial DNA variations in patients with Type 2 (non-insulin dependent) diabetes mellitus and a Welsh control population

1999

The LDL-receptor gene point mutation FH-Genoa/Palermo is the most frequent mutation responsible for Familial Hypercholesterolemia in Sicily. The mutation does not introduce or abolish any useful restriction site. We establish a GeneComb-based strategy to identify this mutation in a population of Sicilian unrelated clinically diagnosed FH probands. The method was very sensitive and specific; 12 out of 90 (13.3%) unrelated FH probands were found to carry the FH-Genoa/Palermo mutation. According to these results, the FH-Genoa/Palermo is the more frequent LDL-receptor gene mutation among the Sicilian FH patients. Moreover FH-Genoa/Palermo is the mutation cluster to date more represented in Sout…

Riconoscersi genitori: un compito educativo segnato dalla reciprocità. Recognizing Parents: an educational task marked by reciprocity.

2017

Nowadays the parenting presents unexampled fragilities and different questions than the ones in the past. Many parents feel their educational role as more demanding and complex. The essay reviews sociological and psychological references about some aspects of these new changes, in order to start a pedagogical reflection about the emergence of new family educational relationships. The need of an educational sharing between adults and the rethinking of the concept of parental competence (as a dual entity) are proposed and discussed.

Acogimiento en familia extensa: perfil psicosocial de las familias y de los menores acogidos

2021

[EN] Extended family foster care family is the most frequent protective measure for minors in Spain. The objectives of the present study are to analyze the family profile according to different dimensions, knowing the state of psychosocial health care of minors in foster care and study the relationship between family and minor variables. The sample consisted of 101 families and 121 minors between 6 and 17 years old (M = 10.07; DT = 3.92), living in the province of Valencia. The evaluation was carried out through individual interviews with every family. Results show good functionality of families taking into account the family climate, the level of stress, the educational styles and the supp…
