Trichorhinophalangeal syndrome (TRPS) is rare genetic disorder with autosomal dominant inheritance. The TRPS1 gene is located on the long arm of the eighth chromosome (8q24.12). The phenotype is variable and presents a wide clinical spectrum. Most cases are characterised by thin, sparse scalp hair, distinctive facial dysmorphism, and various skeletal abnormalities, especially of the hands and feet. Characteristic facial features may include a ”pear-shaped” nose, micrognathia, dental anomalies, prominent ears, elongated philtrum, and thin upper vermillion border. In most cases, affected individuals exhibit skeletal abnormalities including brachydactyly and clinodac-tyly, short metacarpals phalanges, short feet and metatarsals, and pectus carinatum and hip joint malformations. Additionally, patients may exhibit short stature.

This report presents four cases of TRPS (three sporadic and one familial). Clinical presentation included typical facial features and vari-ous skeletal abnormalities. Some TRPS symptoms may mimic growth hormone deficiency and other endocrine disturbances. The aim of this article is to deliver TRPS symptomatology. The treatment of TRPS is symptomatic and supportive and requires the coordination of several specialists, including paediatricians, endocrinologists, orthopaedic surgeons, dermatologists, and medical rehabilitation and den-tal specialists. In some cases, recombinant growth hormone therapy may be necessary. Genetic counselling may be of benefit for affect-ed individuals and their families.
