BACKGROUND Hereditary multiple exostosis represents the most frequent bone tumor disease in humans. It consists of cartilage deformities affecting the juxta-ephyseal region of long bones. Usually benign, exostosis could degenerate in malignant chondrosarcoma form in less than 5% of the cases. Being caused by mutations in the predicted tumor suppressor(More)
Deletions of chromosome 22q11.2 have been associated with distinct phenotypes including DiGeorge syndrome (DGS) and velo-cardio-facial (VCFS) syndrome. These diseases result from a failure to form derivatives of the third and fourth branchial arches during development. DGS/VCFS deletions usually encompass about 3 Mb of genomic DNA in more than 90% of(More)
We have isolated a few cDNAs from different human tissues, transcribed from the first intron of HIRA, a gene deleted in the DiGeorge syndrome. These cDNAs are produced by an intronic gene (22k48) which is transcribed by the HIRA opposite strand and is itself arranged in exons and subjected to alternative splicing. The longest continuum cDNA sequence we(More)
PURPOSE Nail-Patella syndrome (MIM 161200) is a rare autosomal dominant disorder characterized by hypoplastic or absent patellae, dystrophic nails, dysplasia of the elbows, and iliac horn. In 40% of cases, a glomerular defect is present and, less frequently, ocular damage is observed. Inter- and intrafamilial variable expressivity of the clinical phenotype(More)
We report the genomic organization, RNA and protein expression patterns of the gene encoding for the human homolog of the yeast ubiquitin fusion-degradation protein-1 (UFD1L). This enzyme is involved in a ubiquitin-dependent proteolytic pathway (UFD), firstly described in yeast. The human UFD1L gene is organized into 12 exons ranging in size from 33 to 161(More)
BACKGROUND Cystic fibrosis (CF) is a multisystem disorder characterised by mutations of the CFTR gene, which encodes for an important component in the coordination of electrolyte movement across of epithelial cell membranes. Symptoms are pulmonary disease, pancreatic exocrine insufficiency, male infertility and elevated sweat concentrations. The CFTR gene(More)
Common variable immunodeficiency (CVID) is considered the most common symptomatic antibody deficiency and, although mainly reported in adults, it may present from childhood. Few data on the impact of TACI defects on the clinical and immunological status of children are available. We screened 42 hypogammaglobulinemic children to investigate the frequency and(More)
Glucose transporter 1 (GLUT1) deficiency syndrome (GLUT1DS) was initially described in the early 90s as a sporadic clinical condition, characterized by seizures, motor and intellectual impairment with variable clinical presentation, and without a known genetic cause. Although causative mutations in SLC2A1 were later identified and much more is known about(More)
