ABSTRACT
Loeys-Dietz syndrome is a rare, autosomal dominant genetic disease, with marfanoid habit,
which belongs to a subset of diseases of the connective tissue with mainly skeletal, ocular, and cardiovascular
involvement. Aneurysms development is characteristic in this pathology. Loeys-Dietz syndrome
is caused by mutations in TGFBR1, TGFBR2, TGFB2, TGFB3 and SMAD3 genes. In this manuscript
is presented the clinical case of a 22-month-old male patient with significant dilatation of the aortic
root and elongated aortic arch is described. The molecular test confirms the diagnosis of Loeys-Dietz
syndrome associated with a mutation in the TGFBR2 gene. This corresponds to the first case reported
in the southwestern Colombian.
