Hypersociability in Williams syndrome result of myelination deficits. People with Williams syndrome (WS) display indiscriminate approach toward strangers in everyday life. The abnormal profile of excessively social behavior represents an important component of the phenotype that may distinguish WMS from other developmental disorders. However, the neural substrates of this hypersociability, i.e., positive attribution bias and increased drive toward social interaction, have not fully been elucidated. Relations between social-perceptual ability in multi- and unisensory contexts, autonomic reactivity, and social functioning in individuals with Williams syndrome.

Linking cognitive neuroscience and molecular genetics: New Williams syndrome. Williams Syndrome, a rare neurodevelopmental disorder that affects about 1 in 10,000 babies born in the United States, produces a range of symptoms including cognitive impairments, cardiovascular problems, and extreme friendliness, or hypersociability. Individuals with Williams syndrome (WS) demonstrate an abnormally positive social bias. It offers considerable insight into the mechanism of facial perception in humans and a further elaboration of the hypersociability observed in patients with Williams syndrome. Williams syndrome (WMS) is a most compelling model of human cognition, of human genome organization, and of evolution. Furthermore, the studies show that the profile is observed across a wide range of ages, and emerges consistently across multiple experimental paradigms.

Williams syndrome hypersociability: A neuropsychological study of the amygdala and prefrontal cortex hypotheses. The aim of this study was to explore whether amygdala dysfunction, abnormally high social salience or frontal lobe dysfunction account for the hypersociability observed in individuals with Williams and Down syndrome. Williams Syndrome, a rare neurodevelopmental disorder that affects about 1 in 10,000 babies born in the United States, produces a range of symptoms including cognitive impairments, cardiovascular problems, and extreme friendliness, or hypersociability. Hypersociability can also occasionally refer to a symptom of Williams syndrome characterized by an unusual willingness to converse with others. Towards the neural basis for hypersociability in a genetic syndrome. 1999 Jun 3;10(8):1653-7. doi: 10.1097/00001756-199906030-00006. 1999 May;22(5):197-207. doi: 10.1016/s0166-2236(99)01397-1. Individuals with Williams syndrome (WS) demonstrate an abnormally positive social bias. Serotonergic innervation of the amygdala is increased in autism spectrum disorder and decreased in Williams syndrome. Lew CH, Groeniger KM, Hanson KL, Cuevas D, Greiner DMZ, Hrvoj-Mihic B, Bellugi U, Schumann CM, Semendeferi K. Mol Autism. These studies of hypersocial behavior in WMS promise to provide the groundwork for crossdisciplinary analyses of gene-brain-behavior relationships. We read with great interest the paper of Riby et al. Of the deleted genes, general transcription factor IIi (Gtf2i) has been linked to hypersociability in WS, although the underlying mechanisms are poorly understood. Williams syndrome, also known as Williams-Beuren syndrome, occurs when people are missing of a chunk of DNA containing about 27 genes. People with Williams syndrome (WS) display indiscriminate approach toward strangers in everyday life. Keywords: Williams syndrome, Hypersociability, Facial emotion, fMRI, Orbitofrontal cortex, Amygdala Introduction Williams syndrome (WS) is a neurodevelopmental disorder characterized by a hemizygous microdeletion of approximately 20 genes, contiguous with the elastin gene on chromosome 7 (locus 7q11.2) (Francke 1999 ). National Library of Medicine Abstract. The team focused more specifically on 25 genes in this study known as Gtf2i and linked that gene to the hypersociability seen in Williams Syndrome.

However, the neural substrates of this hypersociability, i.e., positive attribution bias and increased drive toward social interaction, have not fully been J Med Genet. Williams-Beuren syndrome (WBS), caused by a microdeletion of approximately 21 genes on chromosome 7q11.23, is characterized by unique hypersociability combined with increased non-social anxiety. Abstract. Genome Structure and Cognitive Map of Williams Syndrome, A large-scale validation of the relationship between cross-disciplinary research and its uptake in policy-related documents, using the novel Overton altmetrics database, The MIT Press colophon is registered in the U.S. Patent and Trademark Office. We would like to suggest that the neurologic mechanisms underlying the hypersociability in WS may be attributable to an impaired recognition of facial expressions of threat, a feature that localises to the amygdala. It is mostly caused by the microdeletion 7q11.23, a loss of a fragment of genetic material on chromosome 7. Due to a deletion in chromosome band 7q11.23, subjects have cardiovascular, connective tissue, and neurode-velopmental deficits. Hypersociability in Young Children With Williams Syndrome Teresa F.
