Abstract
The results of the main epidemiological surveys of fragile X syndrome are reviewed. Studies using cytogenetic methods have typically yielded estimates in the 1/1000 to 2000 range whereas more recent investigations relying on molecular biology techniques have provided more conservative estimates of 1/4000 for males and of 1/7000 for females. We then provide estimates of the numbers of French children with the condition. Available French studies suggest that fragile X syndrome is still underrecognized.
