Expansion of Carraro syndrome or a new disorder?

A 6-year-old girl is described with a unique, rare type of tibial hemimelia known as Carraro syndrome (OIMI 275230). There are only two previous reports of this condition in the literature. In our patient, the tibia anomaly was associated with other skeletal abnormalities, hemivertebra and tetralogy of Fallot. This association of malformations has not previously been reported. We conclude that this girl has either a variant of Carraro syndrome or a new syndrome.
