ResumoA síndrome tricorrinofalangiana (STRF) tipo I é uma doença genética rara, relacionada com a mutação no gene TRPS1 do cromossomo 8. É caracterizada por anomalias craniofaciais e distúrbios na formação e maturação da matriz óssea. As características são cabelos ralos e quebradiços, tendência à calvície prematura, nariz bulboso em formato de pera, filtro nasal longo e plano e baixa implantação das orelhas. As alterações esqueléticas mais notáveis são a clinodactilia, as epífises das falanges das mãos em forma de cone, a baixa estatura e as malformações na articulação do quadril. Relata‐se o caso de um adolescente diagnosticado com STRF e encaminhado para avaliação reumatológica em decorrência de queixas articulares.AbstractThe Tricho‐rhino‐phalangeal syndrome (TRPS) type I is a rare genetic disorder related to the TRPS1 gene mutation in chromosome 8, characterized by craniofacial abnormalities and disturbances in formation and maturation of bone matrix. The hallmarks are sparse and brittle hair, tendency to premature baldness, bulbous nose called pear‐shaped, long and flat filter and low ear implantation. The most noticeable skeletal changes are clinodactyly, phalangeal epiphyses of the hands appearing as cone‐shaped, short stature and hip joint malformations. We report a case of a teenager boy diagnosed with TRPS and referred for rheumatologic evaluation due to joint complaints.
