Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering sciences. However, some important feedback mechanisms are still not clearly established. The present study aims(More)
Benign hereditary chorea (BHC) (MIM 118700) is an autosomal dominant movement disorder. The early onset of symptoms (usually before the age of 5 years) and the observation that in some BHC families the symptoms tend to decrease in adulthood suggests that the disorder results from a developmental disturbance of the brain. In contrast to Huntington disease(More)
We describe a 3-month-old female with a de novo interstitial deletion of the long arm of chromosome 1 (1q23-25). Clinical features are failure to thrive, psychomotor retardation, cleft lip and palate, short metacarpals, metatarsals and fingers and a severe congenital heart disease. The four previously reported patients with the same deletion share with ours(More)
The aim of this report is to provide an update on the natural history of the Cri du Chat Syndrome by means of the Italian Register (I.R.). Two hundred twenty patients were diagnosed by standard cytogenetic methods and 112 of these were also characterised by molecular-cytogenetic investigation (FISH). FISH analysis showed interstitial deletions, short(More)
We describe a patient with arterial tortuosity syndrome (ATS), a rare disorder comprising generalized tortuosity and elongation of all major arteries, soft skin, joint laxity, severe keratoconus, and diffuse tortuosity of the carotids and of intracranial arteries. The patient's probably affected brother and sister died at an early age. Cytochemical studies(More)
At chromosome 11p15.5, the imprinting centre 1 (IC1) controls the parent of origin-specific expression of the IGF2 and H19 genes. The 5 kb IC1 region contains multiple target sites (CTS) for the zinc-finger protein CTCF, whose binding on the maternal chromosome prevents the activation of IGF2 and allows that of H19 by common enhancers. CTCF binding helps(More)
OBJECTIVE This study was conducted to report a family affected by benign hereditary chorea in which a large deletion including TTF1, PAX9, and other genes was identified and results in oligodontia. METHODS Clinical and radiological studies of the two affected members (mother and daughter) were used to describe the oligodontia present in both of them. (More)
Immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome is a condition characterized by variable combined immunodeficiency, developmental delay, facial anomalies and a variety of structural chromosomal rearrangements. Recently, aberrations at the molecular level have been described consisting of alterations in the methylation pattern of(More)
We report on a patient with a multiple congenital abnormalities/mental retardation (MCA/MR) syndrome including facial abnormalities, agenesis of the corpus callosum, heart defect, 1st ray anomalies of the upper limb, and ambiguous genitalia, whose phenotype overlaps a previous description of XK syndrome. The patient has a ring chromosome (13) with deletion(More)
