Abstract

Tricho-rhino-phalangeal syndrome (TRPS) is characterized by craniofacial and skeletal malformations including short stature, cone-shaped phalangeal epiphyses and Perthes-like changes of the hip. We describe the response to growth hormone (GH) treatment in a boy with TRPS. The patient presented at age 3.5 years for evaluation of short stature (−3.2SD). On physical examination, the characteristic facial phenotype of TRPS was noted. Radiographs showed cone-shaped phalangeal epiphyses and bilateral small and fragmented femoral heads. The diagnosis was confirmed by Sanger sequencing of the TRPS1 gene. Two GH stimulation tests revealed GH deficiency, and GH treatment was initiated. Subsequently, growth velocity improved, as did the radiographic appearance of the femoral epiphyses, as seen on sequential pelvis radiographs. This observation suggests the possibility of a beneficial effect of GH treatment on both height and epiphyses status in TRPS patient with GH deficiency. Further studies are needed to support the observation.
