Arthrogryposis, renal dysfunction, cholestasis syndrome in a neonate: an uncommon association of common problems

Abstract

A male infant born out of non-consanguineous marriage to a primigravida presented to us as his third hospitalisation with ichthyotic lesions all over the body, cholestatic jaundice, multiple joint contractures and a history of recurrent sepsis. Blood and urine investigations revealed Fanconi syndrome, hypothyroidism and direct hyperbilirubinaemia with elevated liver enzymes and normal gamma glutamyl transpeptidase levels. The combination of arthrogryposis, renal dysfunction and cholestasis led to the suspicion of arthrogryposis, renal tubular dysfunction, cholestasis (ARC) syndrome, which was then proved by genetic testing. The baby was managed conservatively with respiratory support, antibiotics, multivitamins, levothyroxine and other supportive measures but succumbed to the illness on day 15 of hospitalisation. Genetic analysis using next-generation sequencing was confirmatory of a homozygous mutation in VIPAS39 gene leading to ARC syndrome type 2 in the present case. Genetic counselling was provided and prenatal testing was advised to the parents for future pregnancies.
