Genética e linguagem na síndrome de Williams-Beuren: uma condição neuro-cognitiva peculiar

Abstract: Background: genetic, cognitive and language aspects of the Williams-Beuren Syndorme (WBS). Aim: to present a review of the literature about WBS, highlighting its genetic, cognitive and language characteristics. Conclusion: the literature indicates that although the etiology of WBS is known, early diagnosis is difficult due to the great variability of its clinical characteristics. This great phenotypic variability has been associated to a deletion of several genes in region 7q11.23 which includes the elastin ge… Show more

“…Foi descrita pela primeira vez em 1961 por um médico neozelandês, Dr. J. C. P.Williams, quando verificou que um grupo de pacientes pediátricos possuía sintomas parecidos, problemas cardiovasculares, rostos com características semelhantes, atraso mental moderado, dificuldade para ler, escrever e efetuar operações matemáticas (ROSSI et al, 2006).…”

“…Previous studies registered incidence rates of 1:20.000 to 1:50.000 live births and prevalence between 1:7.500 and 1:20.000 live births (Meyer-Lindenberg et al, 2006;Sugayama et al, 2007). Initially, the diagnosis of the syndrome is based on clinical criteria such as typical facial dysmorphism during childhood (flat mid-face, periorbital fullness or swelling, upturned nose, prominent cheeks); cardiovascular diseases (supravalvar aortic stenosis); connective tissue and calcium level alterations (Cardoso-Martins & Silva, 2008;Herreros et al, 2007;Jarvinen-Pasley et al, 2008;Martens et al, 2008;Rossi, et al, 2006Rossi, et al, , 2009. However, diagnostic confirmation can only happen by means of cytogenetic examination (Fluorescence in situ Hybridization Test -FISH) (Sugayama et al, 2007).…”
