ILHAN, Ozkan et al. Arthrogryposis-renal tubular dysfunction-cholestasis syndrome: a cause of neonatal cholestasis. Case report. Arch. argent. pediatr. [online]. 2016, vol.114, n.1, pp.e9-e12. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2016.e9.

Arthrogryposis-renal dysfunction-cholestasis syndrome is a rare lethal disorder that involves multipl organ system. It is inherited autosomal recessive and caused by defects in the VPS33B and VIPAR genes. Three cardinal findings of this syndrome are arthrogryposis, renal tubular dysfunction and cholestasis.The other organ involvements including ichthyosis, central nervous system malformation, platelet anomalies, congenital heart defects and severe failure to thrive are sometimes associated with this syndrome. Clinical findings, organ biopsy and mutational analysis can help for diagnosing but there is no curative treatment except supportive care. Several symptoms of this condition are already usually present in the neonatal period: arthrogryposis, neonatal cholestasis, skin lesions, among others. Usually survival is until the first year of life. We present a newborn whose evolution was rapidly fatal.
