INTRODUCTION: Williams syndrome (WS), an autosomal dominant condition linked to gene deletions on chromosome 7, can cause supravalvular aortic narrowing and death. WS-associated mutations are believed to disrupt arterial elastin fibers, causing smooth muscle malformation, endomysial fibrosis and severe hypertension. Previous studies demonstrated arterial ultrastructural anomalies in adult WS patients. It is not presently known if the arterial phenotype of WS is also present in utero. CASE REPORT: A 34-week stillborn was delivered to a 28-year-old with genetically confirmed WS...

Williams syndrome is a rare neurodevelopmental disorder characterized by mental retardation, growth deficiency, hypercalcemia, cardiac defects, and a distinctive facial appearance. Cardiovascular abnormalities are present in approximately 80% of Williams syndrome patients. Surgical treatment is generally performed for supravalvular aortic stenosis, aortic coarctation, pulmonary artery stenosis, or ventricular septal defect. In rare cases, diffuse hypoplasia of the aortic arch with a normal left ventricular outflow tract and ascending aorta may be diagnosed in early childhood...

There are two basic stages of fine motor learning: performance gain might occur during practice (online learning), and improvement might take place without any further practice (offline learning). Offline learning, also called consolidation, has a sleep-dependent stage in terms of both speed and accuracy of the learned movement. Sleep spindle or sigma band characteristics affect motor learning in typically developing individuals. Here we ask whether the earlier found, altered sigma activity in a neurodevelopmental disorder (Williams syndrome, WS) predicts motor learning...

Descriptions of individuals with Williams syndrome (WS) and co-morbid major depressive disorder (MDD) with psychotic features have not appeared in the literature. In addition to reviewing previous reports of psychotic symptoms in persons with WS, this paper introduces clinical histories and therapeutic management strategies for three previously unreported adults with WS diagnosed with co-morbid MDD with psychotic features. Co-morbid medical disorders common in WS are highlighted with regard to safe and appropriate pharmacological treatment...

Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged...

Anxiety is a prevalent mental health issue for individuals with Williams syndrome (WS). Relatively little is known about the developmental course of anxiety, or how it links with core features of WS, namely social and executive functioning (EF). In this study, parent-reports of anxiety were compared across a 4-year period (N = 17), and links between anxiety, social and EF were explored from concurrent parent-reports (N = 26). Results indicated that high anxiety persisted over time, and anxiety was related to impairments in both social and executive functioning...

An infant with coarctation of the aorta and Williams syndrome was noted to have petechiae in cardiology clinic prior to planned surgical intervention. Workup revealed acquired von Willebrand syndrome secondary to the high shear force generated by the aortic coarctation. He was treated with intra- and postoperative Humate P; there were no postoperative bleeding complications. His acquired von Willebrand syndrome resolved postoperatively.

Williams syndrome (WS) is a rare neurodevelopmental disorder with a well-described, known genetic etiology. In contrast to Autism Spectrum Disorders (ASD), WS has a unique phenotype characterized by global reductions in IQ and visuospatial ability, with relatively preserved language function, enhanced reactivity to social stimuli and music, and an unusual eagerness to interact socially with strangers. A duplication of the deleted region in WS has been implicated in a subset of ASD cases, defining a spectrum of genetic and behavioral variation at this locus defined by these opposite extremes in social behavior...

BACKGROUND: Although sleep problems are well characterized in preschool- and school-age children with neurogenetic syndromes, little is known regarding the early emergence of these problems in infancy and toddlerhood. To inform syndrome-specific profiles and targets for intervention, we compared parent-reported sleep problems in infants and toddlers with Angelman syndrome (AS), Williams syndrome (WS), and Prader-Willi syndrome (PWS) with patterns observed among same-aged typically developing (TD) controls...

Objective: This study examined the spontaneous use of allocentric and egocentric frames of reference and their flexible use as a function of instructions. Method: The computerized spatial reference task created by Heiz and Barisnikov (2015) was used. Participants had to choose a frame of reference according to three types of instructions: spontaneous, allocentric and egocentric. The performances of 16 Williams Syndrome participants between 10 and 41 years were compared to those of two control groups (chronological age and non-verbal intellectual ability)...

BACKGROUND: Numerous studies have assessed the socio-cognitive profile in Williams syndrome (WS) and, independently, in 22q11.2 deletion syndrome (22q11.2DS). Yet, a cross-syndrome comparison of these abilities between individuals with these two syndromes with known social deficits has not been conducted. METHODS: Eighty-two children participated in four study groups: WS (n = 18), 22q112.DS (n = 24), age-matched individuals with idiopathic developmental disability (IDD; n = 20) and typically developing (TD) controls (n = 20)...

Supravalvular aortic stenosis is an uncommon but well characterized congenital narrowing of the ascending aorta above the level of the coronary arteries. It can be a familial disorder, can occur sporadically, or can be associated with Williams syndrome. We are reporting a very rare presentation of supravalvular aortic stenosis with associated left ventricular diverticulum and cleft mitral valve. Repair consisted of resection of the ascending aorta, patch augmentation of the aortic root, and mitral valve repair...

This study describes the profile of repetitive behaviour in individuals with Williams syndrome, utilising cross-syndrome comparisons with people with Prader-Willi and Down syndromes. The Repetitive Behaviour Questionnaire was administered to caregivers of adults with Williams (n = 96), Prader-Willi (n = 103) and Down (n = 78) syndromes. There were few group differences, although participants with Williams syndrome were more likely to show body stereotypies. Individuals with Williams syndrome also showed more hoarding and less tidying behaviours than those with Down syndrome...

OBJECTIVE: Sleep disorders are common in individuals with Williams syndrome (WS), and sleep disturbance has a significant negative effect on attention, learning, and behavior. The use of sleep-inducing medicine in individuals with WS has not been widely investigated. The objective of this study was to evaluate the use and effectiveness of sleep medications among a large sample of individuals with WS by parent survey. METHODS: A survey of the use and effectiveness of sleep medications was completed by 513 (of 2846) members of the Williams Syndrome Association...

Hypercalcemia is defined as a serum calcium concentration that is greater than two standard deviations above the normal mean, which in children may vary with age and sex, reflecting changes in the normal physiology at each developmental stage. Hypercalcemic disorders in children may present with hypotonia, poor feeding, vomiting, constipation, abdominal pain, lethargy, polyuria, dehydration, failure to thrive, and seizures. In severe cases renal failure, pancreatitis and reduced consciousness may also occur and older children and adolescents may present with psychiatric symptoms...

Louise Ewing, Emily K Farran, Annette Karmiloff-Smith, Marie L Smith
Detailed analysis of expression judgments in Williams syndrome reveals that successful emotion categorization need not reflect "classic" information processing strategies. These individuals draw upon a distinct set of featural details to identify happy and fearful faces that differ from those used by typically developing comparison groups: children and adults. The diagnostic visual information is also notably less interlinked in Williams syndrome, consistent with reports of diminished processing of configural information during face identity judgments...

BACKGROUND: Service responses to behaviour phenotypes include care by expert clinicians, syndrome-specific clinics, disability-specific mental health services and generic mental health services. While these services contribute to care, they are often of limited accessibility. METHODS: We describe a population-wide public health intervention aimed at increasing the accessibility of services to the target population. Stepping Stones Triple P (SSTP) is a public health intervention of known efficacy in reducing behaviour problems when delivered to parents of children aged 0-12 with mixed developmental disabilities...
