An infant with Cholestasis and Refractory Electrolyte Abnormalities.

Arthrogryposis-renal dysfunction-cholestasis (ARC) is a rare multisystem disorder caused by mutations in the VPS33B gene, which in turn lead to a premature truncation of the gene product. This autosomal recessive disease has variations in phenotype. We report an infant girl who had severe presentation in the form of dysmorphic features, abnormal hearing assessment and refractory electrolytes disturbances. She was a product of consanguineous marriage with family history of similar presentation. The child passed away at age of 6 months due to aspiration pneumonia. [ABSTRACT FROM AUTHOR]
