Summary

Steel syndrome is an ultra-rare autosomal recessive disease affecting primarily the skeletal system. It is characterized by short stature, bilateral hip and radial head dislocations, carpal coalitions, scoliosis and pes cavus. Other features of the disease are facial dysmorphism, long oval face, prominent forehead, hypertelorism, macrocephaly, low-lying ears, brachydactyly or hearing loss. Steel syndrome is caused by mutations in the Col27A1 gene encoding the pro-alpha chain of fibrillar collagen type XXVII. We report an extremely rare case of an 8-year-old girl with mild skeletal dysplasia, constitutively delayed growth, hypertelorism and facial dysmorphism. In the patient, we identified the presence of two unknown heterozygous variants in the Col27A1 gene by whole exome sequencing: c.1741C>T, p.(Gln581Lys) and c.2858C>T, p. (Pro953Leu). At our department, we diagnosed the second case of Steel syndrome in Europe and at the same time it is the first case of this rare disease in the Slavic population.
