Abstract

We report a 7 1/2-year-old girl with an approximately 9.5 Mb duplication of proximal 17p. Her clinical features include moderately severe developmental delay, absence of speech, talipes, congenital dislocation of the hips, premature adrenarche, dysmorphic facial features, deep palmar creases, and signs and symptoms of peripheral neuropathy consistent with Charcot-Marie-Tooth disease type 1A (CMT1A). Chromosome analysis revealed a partially duplicated 17p with two centromeres on the derivative chromosome. Fluorescence in situ hybridization (FISH) analysis demonstrated the tandemly duplicated segment spans 17p10-p12, including the entire Smith-Magenis syndrome (SMS) critical region and a porti..
