Clinical and radiographic evaluation results were compatible with Camurati-Engelmann disease and the diagnosis was confirmed by mutation analysis (c.652C > T [p.Arg218Cys]).
CED is caused by various missense mutations in the TGFB1 gene that encodes TGFbeta1, the most common of which is an arginine-cysteine amino acid change at codon 218 (R218C) in the latency-associated peptide domain of TGFbeta1.
Genetic analysis of the TGFB1 gene revealed a heterozygous missense mutation p.R218C in exon 4 of chromosome 19q13.1-q13.3 in a 14-year-old girl who presented with typical symptoms of CED, hyperprolactinaemia and menstrual irregularity.
