Trichorhinophalangeal syndrome (TRPS) type I is a rare autosomal dominant disorder, caused by mutations in the TRPS1 gene. It is characterized by slowly growing hair, craniofacial manifestations and orthopedic abnormalities. We present a 17-year-old female of Ukrainian origin who presented to the hair clinic with the complaint of hair loss. Further examination revealed the presence of craniofacial features characteristic for TRPS type I. Sequence analysis of the TRPS1 gene revealed a novel c. 2396_2397 insG frameshift mutation in exon 5, leading to a premature stop at codon 800. This case underlines the importance of the hair phenotype to the diagnosis of this syndrome and emphasizes the fact that when encountered with a severe alopecia in young age, the possibility of a congenital hair disease should always be borne in mind.
