Daughter and mother with orofaciodigital syndrome type 1 and glomerulocystic kidney disease.

A 35-year-old woman was admitted to our hospital for evaluation of end-stage renal failure. Diagnostic imaging, including ultrasonography and magnetic resonance imaging, showed polycystic kidneys and peribiliary hepatic cysts, but the renal cysts were isointense and her kidneys were smaller than the end-stage kidneys of patients with autosomal dominant polycystic kidney disease. Glomerulocystic kidney disease was diagnosed by renal biopsy. Clinical examination revealed findings such as a missing maxillary canine, lingual anomalies, and brachydactyly. Genetic testing gave a diagnosis of orofaciodigital syndrome type 1 with a 5 nucleotide deletion indicating a frameshift mutation in exon 9. The patient's mother had the same mutation and similar clinical findings. This case is useful for understanding kidney and liver involvement in orofaciodigital syndrome type 1.
