Twenty-five medical centers and the Prader-Willi Syndrome (PWS) Association collaborated on a study which attempted to identify all people with genetically confirmed diagnosis of PWS living in Italy. Investigators of the participating centers contacted PWS subjects and/or their family, filled in a specially developed form with the required data and(More)
OBJECTIVE Wolfram syndrome is an autosomal recessive neurodegenerative disorder characterized by diabetes insipidus, diabetes (nonautoimmune), optic atrophy, and deafness (a set of conditions referred to as DIDMOAD). The WFS1 gene is located on the short arm of chromosome 4. Wolfram syndrome prevalence is 1 in 770,000 live births, with a 1 in 354 carrier(More)
The aetiology of impaired growth hormone (GH) secretion in Prader-Willi syndrome (PWS) remains controversial due to the common occurrence of obesity. To further clarify whether suboptimal GH secretion in PWS is an artefact of excess weight, we evaluated both GH immunological activity and GH bioactivity after arginine administration in 23 non-obese PWS(More)
Craniosynostosis is determined by the precocious fusion of one or more calvarial sutures leading to an abnormal skull shape. Additionally, nodular heterotopia is a disorder of neuronal migration and/or proliferation. We describe a very rare multiple congenital anomalies (MCA) syndrome in which craniosynostosis is associated with bilateral periventricular(More)
We report on a follow-up evaluation of a male with a phenotype including craniosynostosis, periventricular nodular heterotopia, and neurodevelopmental delay. He was initially assigned a clinical diagnosis of Fontaine-Farriaux syndrome (FFS) as an infant although now, with improved delineation of this entity, it is evident that this diagnosis is not(More)
Clinical criteria for the diagnosis of Prader-Willi Syndrome (PWS) were established by consensus in 1993 (Holm et al.). Specific molecular testing is now available and the purpose of diagnostic criteria has shifted to identify individuals to test, thus avoiding the expense of unnecessary analysis. The aim of this study was to find clinical indicators to(More)
Prader-Willi syndrome (PWS) is the most frequent cause of secondary obesity, characterized by neonatal hypotonia, dysmorphic facies, acromicria, hypogonadism, stunted growth, obesity, behavioural disturbances and cognitive impairment. Clinical diagnosis is confirmed by alteration of imprinted genes on the proximal long arm of chromosome 15 (15q11-13) for(More)
