摘要
Objectives: Camurati-Engelmann disease (CED) is a rare form of progressive bone dysplasia due to mutations in the transforming factor gene TGFB1 on chromosome 19q13.1-q13.3. Endocrine complications such as osteoporosis, vitamin D deficiency, delayed puberty and hypogonadotrophic hypogonadism may be present. Methods and results: 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, hyper-prolactinaemia and menstrual irregularity. The patient responded well to prednisone 5 mg/kg per day as well as calcium and vitamin D supplements. Conclusions: The role of p.R218C in TGFB1 on the mechanism of the disease itself and the complications of it in bones and endocrine glands remain unclear. Early recognition as well as a detailed understanding of the pathogenesis of the disease is important for future treatment options and better quality of life of such patients.
