Alagille's syndrome is an infrequent genetic condition with autosomal inheritance and variable expression. The complete form exhibits five clinical signs, chronic intrahepatic cholestasis, characteristic facies, cardiovascular anomalies, posterior embryotoxon, and vertebral defects. If only 3 or 4 of these are present the case is considered as an incomplete form.
The association of Alagille's syndrome with radio-ulnar synostosis is extremely rare. There is only one case described in the indexed literature. A case is presented of Alagille's syndrome with bilateral proximal radio-ulnar synostosis. To the best of our knowledge this is the second reported case of this association.
