Peer reviewed Peer reviewed
Direct linkDirect link
Hamsho, N.; Antshel, K. M.; Eckert, T. L.; Kates, W. R. – Journal of Intellectual Disability Research, 2017
Background: 22q11.2 deletion syndrome (22q11DS) is the second most prevalent genetic syndrome and has a characteristic academic and behavioural phenotype. The primary objective of the current study was to examine the childhood predictors of written expression achievement in adolescents with 22q11DS. Written expression is an important skill that…

Weisman, O.; Feldman, R.; Burg-Malki, M.; Keren, M.; Geva, R.; Diesendruck, G.; Gothelf, D. – Journal of Intellectual Disability Research, 2017
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…

Fahim, C.; Yoon, U.; Nashaat, N. H.; Khalil, A. K.; El-Belbesy, M.; Mancini-Marie, A.; Evans, A. C.; Meguid, N. – Journal of Intellectual Disability Research, 2012
Background: Genetically Williams syndrome (WS) promises to provide essential insight into the pathophysiology of cortical development because its ~28 deleted genes are crucial for cortical neuronal migration and maturation. Phenotypically, WS is one of the most puzzling childhood neurodevelopmental disorders affecting most intellectual…

Antshel, K.; Hier, B.; Fremont, W.; Faraone, S. V.; Kates, W. – Journal of Intellectual Disability Research, 2014
Background: The primary objective of the current study was to examine the childhood predictors of adolescent reading comprehension in velo-cardio-facial syndrome (VCFS). Although much research has focused on mathematics skills among individuals with VCFS, no studies have examined predictors of reading comprehension. Methods: 69 late adolescents…

Dodd, H. F.; Porter, M. A.; Peters, G. L.; Rapee, R. M. – Journal of Intellectual Disability Research, 2010
Background: Indiscriminate social approach behaviour is a salient aspect of the Williams syndrome (WS) behavioural phenotype. The present study examines approach behaviour in pre-schoolers with WS and evaluates the role of the face in WS social approach behaviour. Method: Ten pre-schoolers with WS (aged 3-6 years) and two groups of typically…

Shashi, V.; Veerapandiyan, A.; Schoch, K.; Kwapil, T.; Keshavan, M.; Ip, E.; Hooper, S. – Journal of Intellectual Disability Research, 2012
Background: Although distinctive neuropsychological impairments have been delineated in children with chromosome 22q11 deletion syndrome (22q11DS), social skills and social cognition remain less well-characterised. Objective: To examine social skills and social cognition and their relationship with neuropsychological function/behaviour and…
