Abstract

HAZAN, Filiz et al. Triehorhinophalangeal syndrome type II presenting with short stature in a child. Arch. argent. pediatr. [online]. 2016, vol.114, n.6, pp.e403-e407. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2016.e403.

Trichorhinophalangeal syndrome type II (TRPSII) (synonym: Langer-Giedon syndrome) is a rare autosomal dominant contiguous gene syndrome, resulting from a microdeletion encompassing the EXT1 and the TRPS1 gene at 8q24 (MIM#150230). This syndrome combines the clinical features of two autosomal dominant disorders, trichorhinophalangeal syndrome type I (MIM#190350) and hereditary multiple osteochondromas type I (MIM # 133700). TRPSII is characterized by sparse scalp hair, a long nose with a bulbous tip, long flat philtrum, cone-shaped epiphyses of the phalanges, retarded bone age in infancy and multiple cartilaginous osteochondromas. We report a Turkish patient who had the clinical features and skeletal signs of TRPSII in whom a 13.8Mb deletion in 8q23.1- 8q24.13 was detected.

Keywords : Trichorhinophalangeal syndrome type II; Chromosome deletion; Short height.
