The much-quoted prevalence figure of 1:1,000 males for fragile X syndrome is an overestimate in a mixed ethnic population. A reexamination of the individuals from whom those data were derived using molecular diagnostic techniques demonstrates a more realistic figure of 1:4,000 males.

β¦ Synopsis
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 differential diagnosis of children with mental retardation and excess growth. This review highlights the most recent advances in the field of fragile X research. Β© 2005 WileyβLiss, Inc.
