ABSTRACT
El síndrome FATCO, por las siglas en inglés de aplasia fibular (Fibular Aplasia), campomelia de tibia (Tibial Campomelia) y oligosindactilia (Oligosyndactyly), es un conjunto de malformaciones óseas, en las que la alteración se centra en los huesos de la pierna. Es una entidad rara y hay pocos casos descritos en la Literatura internacional, y, hasta ahora, no se ha descrito ningún caso en Colombia. Presentamos aquí el caso de un recién nacido de sexo masculino con signos clínicos de manera prenatal y posnatal consistentes con síndrome FATCO sin otras malformaciones asociadas. Exponemos también una breve discusión sobre las diferentes malformaciones óseas y otros casos de FATCO en el mundo.
The FATCO syndrome, (Fibular Aplasia, Tibial Campomelia and Oligosyndactyly) are bone malformations with main alteration in lower limbs. It is a rare entity and there are few cases reported in international literature, and so far there are not published cases in Colombia. Here we present a case of a male newborn with prenatal and postnatal signs consistent with FATCO syndrome without other organs malformations, and there is a brief discussion about this syndrome and other different malformations associated with it.

Campomelic dysplasia (CD; OMIM #114290), a rare form of congenital short-limbed dwarfism, is due to mutations in SOX9, a member of the SOX (SRY-related HMG box) gene family. Multiparous mother at 38 weeks' gestation delivered a 3,272 g baby boy with characteristic phenotypes including bowing of the lower limbs, a narrow thoracic cage, 11 pairs of ribs, hypoplastic scapulae, macrocephaly, flattened supraorbital ridges and nasal bridge, cleft palate, and micrognathia. He underwent a tracheostomy at the age of three months for severe laryngomalacia after a number of repeated hospitalizations due to respiratory problems and died at the age of four months from progressive respiratory failure. He was diagnosed as having CD based on a novel frameshift mutation (p.Gln458ArgfsX12) in the SOX9 gene, the mutation which has not yet been reported in Korea.
