Metaphyseal dysostosis and congenital nystagmus in a male infant with the fragile X syndrome.
A 14-month-old male with congenital nystagmus, sparse scalp hair, protuberant ears, developmental delay, and radiologic manifestations of mild metaphyseal dysostosis was coincidentally found to have the fra(X) chromosome in 67% of analyzed metaphases. This observation underscores the need for fra(X) analyses in children with developmental deficit of unknown cause.
