Arthrogryposis, renal tubular acidosis and cholestasis (ARC) syndrome: two new cases and review

Abstract

ARC syndrome, the association of arthrogryposis, renal tubular dysfunction and cholestasis, is a rare genetic disorder. We report two Saudi infants from two different families with ARC syndrome. Magnetic resonance imaging of the brain of one of the infants showed lissencephaly, a previously unreported finding in this syndrome. We also review 39 ARC cases reported in the literature using the Medline database from January 1966 to September 2004.
