“…If they want something, they manipulate others. For instance they take an adult by the hand and guide them to what is wanted and push a hand away if they do not want help (see Joleff & Ryan, 1993;and Didden, Korzilius, Duker, & Curfs, 2004). Children with AS hardly use nonverbal behaviour like gestures and pointing for joint action and joint attention.…”

Genomic imprinting and communicative behaviour: Prader-Willi and Angelman syndrome

The kinship theory of genomic imprinting predicts that imprinted genes affect mother-child and child-child interactions. According to this theory paternally expressed genes will promote behaviours that increase costs of maternal investments and enable children to compete with siblings. Maternally expressed genes will promote behaviours that reduce the mother's costs of child-rearing and enable children to engage in collaborative actions. PraderWilli syndrome and Angelman syndrome are caused by the absence of expression of imprinted genes in 15q11-q13. Children with Prader-Willi syndrome lack the expression of paternally expressed genes; children with Angelman syndrome lack maternally expressed genes. The current paper discusses the role of imprinted genes in the development of communicative behaviours during the transition from breastfeeding to (consuming) solid food. Its focus is the possible role of imprinted genes in the development of empathy out of (reactive) crying, and in the development of behaviours necessary for joint action. Observed behavioural differences between children with Angelman and Prader-Willi syndrome, and data from mouse models on the effects of imprinted genes on brain development, are used to explore possible effects of imprinted genes.

show abstract

“…The aim of the present study was to investigate the development of communicative and functional abilities in subjects with WHS in a similar way to comparable research on other genetic syndromes (i.e. Down's syndrome, Williams syndrome, Prader–Willi syndrome and Angelman syndrome; Jollef & Ryan 1993; Penner et al 1993; Buntinx et al 1995; Giannotti & Vicari 1999; Andersen & Stromme 2001). By identifying the level of severity and the qualitative characteristics of cognitive, communicative and functional impairment, it will then be possible to develop specific rehabilitative intervention programmes suitable for increasing the communicative opportunities of these patients, as well as their ability to actively and autonomously participate in various life contexts (e.g.…”
