title: Pronounced short stature in a girl with tricho-rhino-phalangeal syndrome II (TRPS II, Langer-Giedion syndrome) and growth hormone deficiency.
abstract: We report on a 10-year-old girl with tricho-rhino-phalangeal syndrome type II (TRPS II) and pronounced short stature (-4.8 SD). The patient has an interstitial chromosome 8q24.1 deletion of 12-15 Mb. The deletion spans all genes from CSMD3 to at least ANXA13 including the TRPS1 and EXT1 genes, which are responsible for the TRPS II phenotype. In addition to the features of TRPS II, the patient had growth hormone (GH) deficiency with diminished response in three stimulation tests. Therapy with 0.2 mg GH/kg/week led to an increase of growth velocity from 2.5 to 6.6 cm/year. To our knowledge, such a combination of TRPS II and GH deficiency has not yet been described.
