Consistency between research and clinical diagnoses of autism among boys and girls with fragile X syndrome: Rates of autism in fragile X syndrome

Abstract

However, relatively little is known about the rates of clinical diagnoses in FXS and whether such diagnoses are consistent with those performed in a research setting using gold standard diagnostic tools
