Imprint switching on human chromosome 15 may involve alternative transcripts of the SNRPN gene
1996
Imprinting on human chromosome 15 is regulated by an imprinting centre, which has been mapped to a 100–kb region including exon 1 of SNRPN. From this region we have identified novel transcripts, which represent alternative transcripts of the SNRPN gene. The novel exons lack protein coding potential and are expressed from the paternal chromosome only. We have also identified intragenic deletions and a point mutation in patients who have Angelman or Prader–Willi syndrome due to a parental imprint switch failure. This suggests that imprint switching on human chromosome 15 may involve alternative SNRPN transcripts.
Indication of a common origin of German and American Families with Familial Amyloidneuropathy Typ II
1999
Abstract The classification of familial amyloid neuropathies (FAP) is traditionally based on clinical and regional aspects. In the last 10 years more than 40 mutations of the transthyretin gene have been found to be responsible for different clinical forms of amyloidosis including familial FAP.FAP II is caused by a mutation on the codon 58 of the transthyretin gene. Only two american kindreds (the Maryland/German and the Ohio family) have previously been reported with FAP II starting in the 3rd or 4th decade by sensory disturbances of the hands typically as a carpal tunnel syndrome. We report on a german family with FAP II from the rhine river area south of Mainz. Four members with typical …
Novel <b><i>VANGL1</i></b> Gene Mutations in 144 Slovakian, Romanian and German Patients with Neural Tube Defects
2012
Neural tube defects (NTDs) are a group of congenital malformations of the central nervous system occurring at an average rate of 1 per 1,000 human pregnancies worldwide. Numerous genetic and environmental factors are discussed to be relevant in their etiology. In mice, mutants in >200 genes including the planar cell polarity (PCP) pathway are known to cause NTDs, and recently, heterozygous mutations in the human <i>VANGL1</i> gene have been described in a small subset of patients with NTDs. We performed a <i>VANGL1</i> mutation analysis in 144 unrelated individuals with NTDs from Slovakia, Romania and Germany and identified 3 heterozygous missense mutations: c.613…
Hutchinson Gilford Progeria Syndrome: A Therapeutic Approach via Adenoviral Delivery of CRISPR/cas Genome Editing System
2015
Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare human genetic disease caused by mutations in the LMNA gene. LMNA codes for structural components of the nuclear lamina. Alterations of nuclear lamina lead to a very variable class of diseases known as laminopathies. In detail, HGPS manifests a severe premature ageing phenotype due to the accumulation of a dominant negative form of lamin-A called progerin. With current treatments, the life expectancy of HGPS patients does not exceed their second decade. Death is usually due to cardiovascular complications. Recently, a new technology for mammals in vivo gene editing has been developed: the clustered regularly interspaced short palindromic …
αααanti-4.2 Haplotype and heterozygous β° thalassemia in a Sicilian family
1985
The presence of the αααanti-4.2 haplotype and heterozygous β° thalassemia in a Sicilian family is described. These findings confirm the presence in Italy of a leftward deletion (−α4.2) and indicate that this may not be rare. Furthermore, although the β thalassemia determinant in this family has a severe expression, the interaction with the triplicated α gene does not necessarily express itself as thalassemia intermedia.
Epidemiological study of nonsyndromic hearing loss in Sicilian newborns
2007
Deafness is caused by a variety of facts, genetic and environmental. Regarding the acquired causes, deafness can be the consequence of prenatal infections, acoustic or cerebral trauma, and the use of ototoxic drugs. Deafness can be the only manifestation (nonsyndromic forms) or it may occur together with other phenotypic findings (syndromic forms). The majority of nonsyndromicdeafness has a genetic basis [Van Camp et al., 1997]. In recent years, deafness and hearing loss have assumed a clinical importance in the study of congenital disorders [Morton et al., 1991]. The clinical interest for hearing loss is supported by the social impact that this disorder has; if not treated, delays in the d…
Sporting Activities and Quality of Life in Children With Hemophilia: An Observational Study.
2016
Sports activities are part of multidisciplinary treatments in people with hemophilia. Aim: The objective of this study was to assess the incidence of sports activities in the quality of life as perceived by children with hemophilia. Methods: A total of 53 children with hemophilia aged 7 to 13 years and 51 children without hemophilia were evaluated. The perception of quality of life, clinical variables, and the frequency of sports activities were registered. The joint condition of patients with hemophilia was measured with the Spanish version of the Haemophilia Joint Health Score. Results: There were no significant differences in the perception of quality of life between children with hemoph…
Estudio del desarrollo del macizo craneaofacial y del globo ocular en un modelo de hipotiroidismo congénito-neonatal 2en la rata
2000
RESUMEN Nuestro objetivo es identificar factores que regulen procesos de diferenciación y proliferación celular en el globo ocular y tejidos anexos, cuya alteración estuviera relacionada con la aparición de dismorfogénesis ocular. Basándonos en publicaciones que demuestran que la hormona tiroidea (HT) modula la expresión génica en el cerebro, hemos estudiado si el hipotiroidismo congénito-neonatal (HPCN) inducido experimentalmente en la rata gestante (G) interfiere en el desarrollo embrionario de estructuras del macizo craneofacial y esbozo ocular y particularmente en la ontogénesis de la retina. El HPCN se logró mediante administración ininterrumpida a las ratas en el agua de bebida, desde…
Observatoire francophone des néoplasies endocriniennes multiples de type 1. Un outil du Groupe d'étude des Tumeurs Endocrines (GTE)
2007
Wermer's syndrome or Multiple Endocrine Neoplasia Type-1 (MEN1) is an autosomal dominant inherited disease, related to mutations in MEN1, an approximately 10-kb gene encoding menin, localized on chromosome 11q13. The Endocrine Tumor Group (GTE) has set up a MEN1 observatory of 1001 regularly followed MEN1 cases. This observatory aims at registering and evaluating MEN1 cases in a large cohort. Any new study on a particular unexplored aspect of the disease may be proposed by a physician to the GTE. This article describes the way to diagnose a new MEN1 case and to register it. Procedures for participating in a new study are presented. Some original results are quoted.
