Expanding the knowledge about Thauvin-Robinet-Faivre syndrome: a case report with novel clinical findings and review of the literature.

This case report expands the phenotypic spectrum of Thauvin-Robinet-Faivre syndrome (TROFAS, OMIM #617107), a rare autosomal recessive disorder caused by biallelic loss-of-function mutations in the FIBP gene. We describe a patient with genetically confirmed TROFAS who presented with novel clinical features, including non-ossifying fibromas, subglottic tracheal stenosis, intermediate uveitis, and complete atrioventricular block requiring pacemaker implantation. The findings significantly broaden the phenotypic landscape of TROFAS and underscore the need for multidisciplinary management and long-term follow-up.
