A very mild phenotype of Charcot-Marie-Tooth disease type 4H caused by two novel mutations in FGD4
2019
Abstract Background Mutations in the FGD4 gene cause an autosomal recessive demyelinating peripheral neuropathy referred to as CMT4H, characterized by its onset in infancy or early-childhood and its slow progression. Methods The clinical and genetic status of two patients with CMT4H was studied, performing genetic testing with a panel of genes and analysing FGD4 mRNA expression by quantitative PCR. Results Two novel FGD4 variants (c.514delG and c.2211dupA) were identified in two mildly affected Spanish siblings with CMT4H, and with disease onset in late adolescence/adulthood (one of them remaining asymptomatic at 20). On examination, foot deformity was observed without weakness or sensory i…
Recommendations for design and analysis of health examination surveys under selective non-participation
2019
Background The decreasing participation rates and selective non-participation peril the representativeness of health examination surveys (HESs). Methods Finnish HESs conducted in 1972–2012 are used to demonstrate that survey participation rates can be enhanced with well-planned recruitment procedures and auxiliary information about survey non-participants can be used to reduce selection bias. Results Experiments incorporated to pilot surveys and experience from previously conducted surveys lead to practical improvements. For example, SMS reminders were taken as a routine procedure to the Finnish HESs after testing their effect on a pilot study and finding them as a cost-effective way to inc…
SPG10 is a rare cause of spastic paraplegia in European families.
2008
Contains fulltext : 71099.pdf (Publisher’s version ) (Closed access) BACKGROUND: SPG10 is an autosomal dominant form of hereditary spastic paraplegia (HSP), which is caused by mutations in the neural kinesin heavy chain KIF5A gene, the neuronal motor of fast anterograde axonal transport. Only four mutations have been identified to date. OBJECTIVE: To determine the frequency of SPG10 in European families with HSP and to specify the SPG10 phenotype. PATIENTS AND METHODS: 80 index patients from families with autosomal dominant HSP were investigated for SPG10 mutations by direct sequencing of the KIF5A motor domain. Additionally, the whole gene was sequenced in 20 of these families. RESULTS: Th…
The new gene DmX from Drosophila melanogaster encodes a novel WD-repeat protein
1998
DmX is a novel gene from Drosophila melanogaster located on the X chromosome in region 5D5/6-E1. The molecular analysis of the genomic and cDNA sequences of DmX shows that the gene spans appr. 16kb and displays a mosaic structure with 15 exons. The 12kb long DmX transcript is present in Drosophila embryos, larvae and adults of both sexes. The open reading frame of DmX encodes a novel WD-repeat protein, containing at least 30 WD-repeat units. WD-repeat proteins contain a conserved motif of approximately 40 amino acids (aa), usually ending with the dipeptide Trp-Asp (WD). Homologues of the DmX gene exist in other dipteran species, in Caenorhabditis elegans and human, revealing that DmX is an …
Mutations in a new gene, encoding a zinc-finger protein, cause tricho-rhino-phalangeal syndrome type I
1999
Tricho-rhino-phalangeal syndrome type I (TRPS I, MIM 190350) is a malformation syndrome characterized by craniofacial and skeletal abnormalities and is inherited in an autosomal dominant manner. TRPS I patients have sparse scalp hair, a bulbous tip of the nose, a long flat philtrum, a thin upper vermilion border and protruding ears. Skeletal abnormalities include cone-shaped epiphyses at the phalanges, hip malformations and short stature. We assigned TRPS1 to human chromosome 8q24. It maps proximal of EXT1, which is affected in a subgroup of patients with multiple cartilaginous exostoses and deleted in all patients with TRPS type II (TRPS II, or Langer-Giedion syndrome, MIM 150230; ref.2-5)…
Molecular cloning and characterization of the cDNA encoding the rat liver gamma-butyrobetaine hydroxylase
1999
Carnitine biosynthesis from lysine and methionine involves five enzymatic reactions. gamma-butyrobetaine hydroxylase (BBH; EC 1.14. 11.1) is the last enzyme of this pathway. It catalyzes the reaction of hydroxylation of gamma-butyrobetaine to carnitine. The cDNA encoding this enzyme has been isolated and characterized. The cDNA contained an open reading frame of 1161 bp encoding a protein of 387 amino acids with a deduced molecular weight of 44.5 kDa. The sequence of the cDNA showed an important homology with the human cDNA recently isolated. Northern analysis showed gamma-butyrobetaine hydroxylase expression in the liver and in some extend in the testis and the epididymis. During this stud…
Pasireotide treatment reduces cardiometabolic risk in Cushingâs disease patients: an Italian, multicenter study
2018
Purpose: Patients with Cushing’s disease (CD) experience metabolic alterations leading to increased cardiovascular mortality. Recently, the visceral adiposity index (VAI) has been proposed as a marker of visceral adipose tissue dysfunction (ATD) and of the related cardiometabolic risk. We aimed to evaluate the impact of 12-month pasireotide treatment on cardiometabolic risk in CD patients. Methods: This is a multicentre, prospective, and observational study. Sixteen CD patients, referred to the Endocrine Units of the University Hospitals of Messina, Napoli, Padova, and Palermo (Italy), successfully treated with pasireotide for 12 month have been enrolled. In all patients, we assessed anthro…
A Mediated Tolerance of Violence: An Analysis of Online Newspaper Articles and “Below-the-line” Comments in the Latvian Media
2020
A mediated tolerance of violence: an analysis of online newspaper articles and “below-the-line” comments in the Latvian media This article analyses the framing of tolerance of violence in Latvian newspaper articles published online and the reader response “below-the-line” comments to these and how these frames may negatively present and impact those who suffer violence. It makes visible the language used and concepts employed in such cases where someone supports, justifies, or positively perceives violence. The text is based on qualitative media content analysis of 3,166 documents in the Latvian, Russian and English languages from Latvian news sources online published between 2010 and 2018…
Attenuation of disease phenotype through alternative translation initiation in low-penetrance retinoblastoma
2006
Hereditary predisposition to retinoblastoma (RB) is caused by germline mutations in the retinoblastoma 1 (RB1) gene and transmits as an autosomal dominant trait. In the majority of cases disease develops in greater than 90% of carriers. However, reduced penetrance with a large portion of disease-free carrier is seen in some families. Unambiguous identification of the predisposing mutation in these families is important for accurate risk prediction in relatives and their genetic counseling but also provides conceptual information regarding the relationship between the RB1 genotype and the disease phenotype. In this study we report a novel mutation detected in 10 individuals of an extended fa…
Towards early risk biomarkers: serum metabolic signature in childhood predicts cardio-metabolic risk in adulthood
2021
Summary: Background: Cardiovascular diseases may originate in childhood. Biomarkers identifying individuals with increased risk for disease are needed to support early detection and to optimise prevention strategies. Methods: In this prospective study, by applying a machine learning to high throughput NMR-based metabolomics data, we identified circulating childhood metabolic predictors of adult cardiovascular disease risk (MetS score) in a cohort of 396 females, followed from childhood (mean age 11·2 years) to early adulthood (mean age 18·1 years). The results obtained from the discovery cohort were validated in a large longitudinal birth cohort of females and males followed from puberty to…
