Abstract

Arthrogryposis, renal dysfunction, and cholestasis syndrome is a rare autosomal recessive disorder caused by mutations in the VPS33B and VIPAR genes. Most cases are fatal within the first year of life. Here we describe one of the two oldest patients with arthrogryposis, renal dysfunction, and cholestasis syndrome. This is a 12-year-old Hispanic female, from a non-consanguineous parents, diagnosed with an incomplete phenotype of arthrogryposis, renal dysfunction, and cholestasis syndrome with arthrogryposis and renal tubular dysfunction but without cholestasis. At 11 years of age, she was found to have impaired renal function, nephrotic-range proteinuria, Fanconi syndrome, and distal renal tubular acidosis. She also had hypercalciuria, nephrogenic diabetes insipidus, and small kidneys by renal ultrasound. Genetic analysis using whole exome sequencing showed a mutation and a partial deletion in the VPS33B gene. Further studies showed that the mother has a partial deletion in the VPS33B gene. Her medication regimen includes potassium citrate and enalapril.
