In this article, we describe the language and communication problems of individuals with fragile X syndrome (FXS). FXS is a common genetic disorder resulting from a single-gene mutation on the X chromosome. It is associated with a wide spectrum of physical, behavioral, cognitive, and language proble

Abstract
Fragile X syndrome (FXS) is the leading inherited cause of mental retardation. In this article, we review what is known about the language and related problems of individuals with FXS. In doing so, we focus on the syndromeβspecific features of the language phenotype and on the organismic (i.e., genetic and individual neurocognitive and behavioral) and environmental factors associated with withinβsyndrome variation in the phenotype. We also briefly review those aspects of the behavioral phenotype of FXS that are relevant for understanding syndromeβspecific features of, and withinβsyndrome variability in, language. The review includes summaries of research on the prelinguistic foundations for language development and on each of the major components of language (i.e., vocabulary, morphosyntax, and pragmatics). Throughout the review, we point out implications of existing research for intervention as well as directions for future research. Β© 2007 WileyβLiss, Inc. MRDD Research Reviews 2007;13:36β46.

## Abstract Fragile X syndrome, the most common genetic disorder associated with mental retardation is caused by an expansion of the unstable CGG repeat within the __FMR1__ gene. Although overgrowth is not the main hallmark of this condition, the fragile X syndrome is usually included in the differ
In this paper we report on a third patient with Klinefelter syndrome and fragile X. In the Leuven experience the simultaneous occurrence of both conditions is 1:155 (3 fra(X) positive Klinefelter patients in a total number of 465 fra(X) positive males), a concurrence much higher than expected by cha
