<unk>  (also known as fibular aplasia–tibial campomelia–oligosyndactyly (FATCO) syndrome) is a rare genetic disease that causes congenital limb formation. The main characterisation is the aplasia or hypoplasia of bones (mainly the fibula or tibia) of the limb. It is currently presenting in less than 1 in 1,000,000 newborns. It has been known to be more commonly present in males. It was first diagnosed in 2005 by Courtens et al. who recognised the malformations with his present case and four others that were similarly described in literature.
