Do some patients with fragile X syndrome have precocious puberty?

Abstract
We report on an 81½‐year‐old white girl with fra (X) syndrome; she had mental deficiency, hyperactivity, speech disturbances, slightly prominent ears, mild joint laxity and 20% fra (X) expression. Additional findings include idiopathic precocious puberty and a right ovarian cyst. Ovarian cysts have been reported previously in heterozygous females, but to our knowledge idiopathic precocious puberty is a new finding in this syndrome. Whether precocious puberty is a coincidental finding in this patient or a previously unreported manifestation of the fra (X) syndrome is not clear.
