ABSTRACT
Trichorhinophalangeal syndrome (TRPS) is a rare autosomal dominant hereditary disease caused by mutations in the TRPS1 or the EXT1 gene. Patients show 3 different forms (TRPS I-TRPS III) of this condition sharing similar clinical features including sparse hair, a bulbous nose, an elongated philtrum, short stature, and shortened phalanges. A 10-year-old girl presented with sparse hair and thin hair shafts since birth. She also showed a bulbous nose, an elongated philtrum, brachydactyly of the great toes, and a short stature. Radiological examination showed cone-shaped epiphyses and shortened phalanges. Genetic analysis revealed a novel missense mutation c.2759G>C (p.Trp920Ser) in the TRPS1 gene. We diagnosed this patient with TRPS type III. To our knowledge, only 3 reports have described a genetically analyzed TRPS1 gene mutation among the 11 reported cases of TRPS in the Korean literature. Furthermore, we identified a novel missense mutation in the TRPS1 gene.
